There is quite lot tooltips that are simply wrong or confusing. I think all of what i know has been reported but nothing been done so i made little list of few of them to remind HCS...
Templar:
Heroic Throw – Is supposed to silence 2/4 yards around target of jolt but silences 2/4 yards around caster
Spiked Armor – Reflects 10%-40% Incoming damage back at attackers, and incoming means not hit yet so it should reflect damage that havent taken armor into calculation.
I Feel Your Pain/Empathy – Only transfers damage taken by target not aggro, but makes target generate less aggro?
Glaciate – Ally that is targetted by this spell continue taking damage, be it direct hits or Dots.
Assassin:
Massacre – Damage increase by it isnt shown anywhere and it doesnt effect Dots
Ranger:
Napalm – Tooltip on talent tree says burns 25/50/75% of damage over 6 seconds while debuff/Dot on enemy says 15/30/45% over 6 seconds
Call of the Wild – Summon gets stuck and stops attacking from time to time
Mage:
Intense Focus – Should increase total focus by 5%/10% but increases base focus which is 49 at lvl 49 if no points put into it.
Engulf – Outside battleground can only cast on yourself or enemy mob. Spell itself says "Target: Single (Any)" which leads to believe you can cast it on ally.
Void Portal – Summon gets stuck and stops attacking from time to time.
As for prophet talent stuff.. someone who knows more should say it since i only got confused thinking about it.
Other tooltip stuff: Northam Obelisk Blessing states it gives 5% armor but it gives 5% defense.
