I am running 5 durids right now jsut dinged 34 (palying in my spare time), I love them they are so much fun, Right now they are feral spec they just tear mobs up. I can say that when you go malay it can become really tricky and takes lots of pratice getting all clones attacing lots of mashing the /follow command to face them an move then in range to fight. when I get to lvl 40 I am going to reped to Boomkin to try it out, who knows I might go back feral. but when I get to the mid 50 I am going try instances with one feral/tree/3xboomkin. so far lots of fun
