It's no different than the 29s right now... if you play horde your entire perception of how you have to play/react/manage your heals/dps is skewed. The woes of having no actual targets worth healing is rough. BH has a lot of that, horde players that can smash pugs and don't know what to do when real ****az show up... not being an ass, that is just actual fact if you play both factions... its not about who has more twinks this xpac or not. You can even tell this just by talking to people, the horde players just come across as kind of stupid (with enough exceptions to not be a rule) there is just a HUGE "bro mentality" on the horde side "bro, bro, brobrobro check out my dps, bro bro"... the alliance players are just "nice" I guess... except for maybe 1.
For the record it was not this unbalanced for the Alliance last expansion regardless of who says what, this is real bad, as far as the 29s and 39s.
Listening/reading chat when things are not going right for a horde premade is some actual comedy gold.
