General:
- Holy damage resists in pvp. Holy damage can't be resisted by players in any possible way. It only exist in PVE and I think everyone know this. http://www.wowwiki.com/Holy_resistance just to prevent questions.
The source of problem is buffs that grants "all resistance" effect like MotW (mark of the wild druid buff), resistance potions, mage armor, some talent, cloak enchant and etc. http://www.wowwiki.com/Magic_schools_(WoW)#Holy clearly states that such effects dont give holy resistance.
Racial:
- Berserking (Trolls active racial). Supposted to increase your attack\cast speed by 10%(minimal at full heath) to 30% depending on how much hp you missing. Atm it ALWAYS gives you 5% increase on cast speed (where 5% came from at all

- Shadowguard (Troll priest racial spell).
1. This spell supposted to do shadow damage to attacker when a spell, melee or ranged attack hits the caster. It works pretty fine, but when priest use PW:S (Power Word: Shield) on himself all ranged attacks and spells stop procing Shadowguard, as well as some melee abilities (Heroic Strike doesn't proc it, altho Rend or Hamstring or Autos proc it normally). Shadowguard using mechanics identical to Lighting Shield, Touch of Weakness, Thorns, Retri Aura, etc. and procs independently of caster being shielded or not - it procs from attack or spell hitting caster (with or without doing damage) and doesnt proc if attack\spell didnt reach caster for some reason (dodged, parried, missed, being reflected, fully immuned or resisted).
2. Shadowguard damage procs from DoTs damage, altho it shouldn't. Nothing more to say about this part.
Paladin:
- Seal Of Command. Yes, good old SoC - always bugged
