My idea is that bears should be brought back to ruins and have a random spawn rate like they always used to have. The bears have been proven to be useful as they drop items and they have dropped mystery items before. The bear is also useful for combat strategy as you can kick or shockwave an unsuspecting foe attacking the bear causing death or moderate damage.
The one problem there may be is that the bears may target someone higher up than them causing them to walk into the wall. But if the bears were able to attack above them (because they are so large) this problem will not occur.
