Okay, let's just admit, WoW is not an E-sport. 3v3 has next to no real following. The 2v2 arena scene seems to be fairly popular on Streams, class videos, pvp guides, not to mention is the most commonly played format by far. People play 2v2 for Conquest caps, for practice, for passing time, for recognition and most importantly for FUN. Not to mention when it comes to watching it, 2v2 seems much less of a clusterfuck then 3v3.
While 3v3 seems to cumbersome, there aren't any real honest to god rewards/incentives, and healing in PvP seems to be balanced around the output in 3v3, which completely breaks 2v2, and makes 1v1 utter FotM around what can kill healing hybrids and healers.
5v5 seems to be an utterly dead bracket.
Would you say that it is time to start balancing things around 2v2, by first toning down healing, then gutting CC and balancing damage around that, so the pvp meta game will once again be about meaningful choices rather then FotM and Zerg?
