I see a lot of Ret Paladins use Heal Weapon and Shield in PvP.
I made a char on Blackrock to test it out.
With all procs Judgement does 9k Damage.
With procs i have 3k+ Spellpower and Flashheal heals for 8k+.
Weapon Speed is 1.6 so Seal of Vengeance stacks up super fast.
In Bgs i am basically unkillable by any single player.
Warriors with start gear on Blackrock cant even take 15% of my health.
I dont remember anyone playing like this on retail.
And i have never seen videos from 2010 in which any Paladin played like this.
Is this a privat server thing?
Retail never had the time to fully min-max the classes. Most paladins nowadays have macros to swap to a 1H + Shield for during their opponents' cooldowns / to stall until their own cooldowns are available again. Seal of Vengeance for damage; Seal of Light for recovery. It's essentially the paladin's "Defensive Stance".
