QoL Change: Seal of Blood for Alliance, Vengeance for Horde
Yes I know it's not "Blizzlike" but this gives you the opportunity to correct a wrong...Give Alliance Ret Paladins a reason to exist beyond just being buff whores. Seal of Blood means you take damage which translates to healers actually HEALING you, which gives paladins 10% of the healing gained as mana, due to Spiritual Attunement.
This seal is gamebreaking in TBC, without it, Alliance ret paladins lose 25-30%+ dps for no reason.
I'll get some hate I'm sure, but that's going to be from Blood Elves...Seriously, give Alliance Ret Paladins a chance.
