prot pally is insanely broken right now, find one if you want free glad this season.
running warrior/prot pally in 2s at around 2400.
advantages: nearly 100% win rate vs ass rogues and mages, can kill resto shamans and mw monks in 2 minutes. takes about 5 minutes to kill a disc priest and resto druid.
disadvantages: countered by holy pally and ret pally, theres currently an aff warlock bug that rapes prot paladins right now. ww monks have too much control for you.
running warrior/prot pally/disc at around 2500
advantages: super easy, you just tunnel and durp around. the prot pally and disc do all the work, you just press your 3 damage buttons and move forward. can farm the shit out of mages and ass rogues (which are popular right now), also beats rls easily. you can train just about any healer and they will eventually die with prot pally help. go double time vs mw monk and resto druid, pain train and sharpen blade vs any other healer.
disadvantages: gets absolutely molested by any dot wizard cleave (spriest boomy, aff lock boomy, etc), countered by beast cleave.
