- 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
- 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.
* players and creatures now share the same power regeneration regeneration function
* UpdatePowerRegeneration is now virtual and handles creature and player specific formulas individually
* handle update field flag UF_FLAG_UNIT_ALL to handle UNIT_FIELD_POWER_REGEN_FLAT_MODIFIER and UNIT_FIELD_POWER_REGEN_INTERRUPTED_FLAT_MODIFIER for creatures as well
* all stats and values will now be set before summons are getting added to map
* cleaned up summon spell effect handler to reduce duplicade code
* summoner guids will no longer be set for every minion and correctly handle assigning creator guids instead. These values will serve as fallback guid if there is no summoner guid
* friendly tempsummons will now inherit the guild data of their player and pass them on to further allied summons. This fixes guild specific visuals for creatures such as Guild Battle Standards and Guild Heralds.
Todo: check for regressions
* use a reversed client function to get the power regeneration rate for all types of powers
* unified all player based regeneration updates into a single statsystem helper
* cleaned up unnecessary regeneration timers
* implement power regeneration for alternative powers
* corrected rage gain numbers based on simulationcraft formulas
* according to sniffs, focus is getting updated every second instead of every 4 seconds
* corrected pet focus regeneration from 6 focus per second down to 5 per second
* corrected level 85 stats for Death Knight's Risen Ghoul
* removed an old leftover that was causing Blood Worms to have way too much health
* enabled and use Avoidance for Death Knight Ghouls used in Raise Dead and Army of the Dead
