I'm a new gen player (Droid), but gave my best to pick up from here and there, and with some reading and experiencing, and with some help from members from the forum here, I got the hang of it, and consider myself a quite skilled bear now.

This is the quote that changed my way of playing as a bear, and if any bears read this, you should try do the same:

Iron blood and evade (if its a heavy mob), beckon, taunt, hell scream, (leave a bit for mages/birds to combo), and just when they are about finished you stomp them away. In between the wait you can probably take out 1-2 with slashes. Just rinse and repeat. Your evade/iron blood buffs probably won't be ready in time before you can take the next mob, so I suggest just alternate amounts of huge mobs. First wave is a big one, next one is a smaller one and repeat. Though if your confident in your mage and they can clear fast, you can very much use your evade/iron blood rotation.
This is an epic quote from Ellyidol!
