for PVE, if you want survival, I would go for a Tank Bear. Go for Str of at least 142 (need for lvl 45 str gear), and put some in Dex to increase hit, dodge and crit. May want to consider raising Int to 16 earlier in the game to get the 1 m/s. Overall Bears are fun to play

if you want to be able to kite and tank, go for Bow Bear, go all Dex then it's fun too..

if you want something crazy and not so ordinary, go for the Int bear.. hehe... and he can tank just as well as a Normal Str Bear too

hope this helps
