I am noticing a surge in popularity for paladin teams in 3v3 as well. Anecdotally, we see probably something like 4-5 times as many as we saw (even at the end of) last season, but we may have been floating somewhere above/below all these teams.
I can only assume everyone started getting sick of druids and double physical dps in general? Oh well, good for paladins, and I don't mind fighting them anyway

BoP is a beautiful spell. I guess the ebb and flow of 3v3 will continue, re-rise of the hunter/lock/priest soon?
