- Decoupled Unit logic: split of spell critical chance into done (caster bonuses) and taken (target bonuses), this allows to precalculate caster bonuses on aura apply and then check victim's auras on damage/healing calc
- Made static a bunch of methods (they no longer have this pointer because they are now called from periodic handlers which may or may not have an active caster in world)
- Simplified all AuraEffect bonuses into AuraEffect::_amount, no more duplicated code
- Critical chance and whether or not caster is player owned unit (for resilience calcs) is now saved one level upper, on Aura itself (it's impossible as of 3.3.5 to have different effects with different critical chances)
- Minor cleanup of SPELL_DAMAGE_CLASS_NONE and Arcane Potency (#18813) crit handling
Closes#19876
(cherry picked from commit cb9e72e521)
- PvE combat is now always mutual. UNIT_FLAG_IN_COMBAT is backed by actual references to the units we're in combat with.
- PvP combat is now also tracked, and almost always mutual; spells like Vanish and Feign Death can break this rule. That means we can easily determine a list of players we're fighting.
- By extension, IsInCombatWith now has sensible behavior when invoked on nonplayers.
- Threat and combat systems are no longer the same.
- They still have an enforced relationship (threat implies combat - clearing combat clears threat)...
- ...but we can have combat without threat. A creature (with threat list) isn't considered to be engaged until it has an entry on its threat list...
- ...which means we can now faithfully replicate retail engage behavior. Combat on projectile launch - engagement start on projectile impact. Yay for progress!
- AI method refactor, as already ported in 6113b9d - `JustEngagedWith`, `JustEnteredCombat` and `JustExitedCombat`.
- Vehicle threat is now properly pooled on the main vehicle body (fixes#16542).
- Various edge case bug fixes for threat redirects (Misdirection "cancelling" Vigilance and similar).
- Target re-selection is now significantly faster.
- Fixed a ton of other smaller edge case bugs, probably.
Closes#7951 and #19998.

Core/Spell: The giant CastSpell unclusterfucking (that's a word now) of this generation.
- CastSpell now always takes three arguments - target, spellId, and a struct containing extra arguments
- This struct (CastSpellExtraArgs, see SpellDefines.h) serves as a conglomerate of every previous combination of the 20 billion different CastSpell overloads, all merged into one
- It has some great utility constructors - check them out! All of these can be used to implicitly construct the ExtraArgs object.
- A gajillion refactors to make everything behave the way it always has

Following the work done in #19361 this is the cleanup and improvement of the related logic of waypoint management.
Ref 28050f3#18020
(taking the good parts and ignoring the incomplete work)
(cherry picked from commit 7fff83d675)
Today, we're moving UNIT_FLAG_IMMUNE_TO_PC and UNIT_FLAG_IMMUNE_TO_NPC to higher-level abstraction so combat manager can react to it.
New methods on Unit:
- void SetImmuneTo<All/PC/NPC>(apply, keepCombat = false);
- bool IsImmuneTo<All/PC/NPC>() const;
(cherry picked from commit 74af880217)
* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
(cherry picked from commit e2a1ccd118)
* Pet/Guardian AI hook re-organizing:
- Adjust OwnerAttacked/OwnerAttackedBy hooks on CreatureAI to fire for all owned units, not just player pets. This should allow guardians to more reliably recognize valid targets.
- Kill off the AttackedBy hook. While it was defined in CreatureAI.h as virtual, it was only ever invoked for player pets in specific situations. This makes it classic developer bait.
- Adjust PetAI to use DamageTaken instead of AttackedBy.
- Adjust behavior of AttackStart on PetAI to compensate.
(cherry picked from commit 1660bb7d27)
- Changed self-accessor on GameObjectAI to "me", like UnitAI
- Moved all related functions to AI, now Unit and GameObject have the same function names with identical behaviour
- Remove "OnUpdate" from CreatureScript/GameObjectScript, was never used and we already have AI Update method
- Quest methods no longer return a bool, the return value was used to call the AI version if the ScriptMgr one returned false
- Implemented GameObjectAI::Destroyed hook (was never called), implemented Damaged method
- Rename OnStateChanged to OnLootStateChanged to reflect when it's really called, and created a new hook OnStateChanged that only gets called on GOState change
- Since the functions are now only getting called from AI, made GetAI methods full virtual. (CanSpawn method is anyways going to be used on creatures with AI)

Set in front modifies only the serverside orientation, use with care.
Also check for current focus to prevent things like incorrect damage on casting creatures (ie dragon breath direction change in your face because of some taunt missclick)
(cherry picked from commit 229444b74a)
* In the existing core script, Willix the Importer in Razorfen Kraul says
"Help! Get this $n off of me!" (showing the $n part in his SAY text)
instead of naming the attacker when using his 'SAY_AGGRO1' creature_text.
* With this commit change, unit target is no longer missing for Talk,
making Willix name the attacking unit when he shouts for help.
(cherry picked from commit 6cc267d909)
* Made some changes to kiting mechanics, simplified code and made taunt auras prolong combat no matter the distance from the spawn
Unified some creature despawning code, removed some brutal direct calls in scripts
Don't play death anim on forced despawn
Removed some redundant visibility changes on creature despawn
Fixed possible problem with pet initializing template info from difficulty greater than normal
Properly keep UNIT_FLAG_IN_COMBAT on UpdateEntry call
Moved RegenerateMana function to general Regenerate(Power) function
Fixed increased health regeneration from polymorph for pets
Implemented CREATURE_TYPE_FLAG_GHOST_VISIBLE, those creatures will be properly seen when player is dead also
Removed hackfix from Gaeriyan and Franclorn Forgewright, fixed properly
Simplified ForcedRespawnTime code in ForcedDespawn
Do not allow to assist unit while evading or when enemy is evading
Do not allow to attack other units when evading or when the unit is evading
Corrected distance checking code before creature is allowed to evade, should fix some common problems
Properly return summon position for summoned creatures as their respawn position
Properly stop all moving units on gossip hello, no matter their npc flags
