I'm not sure whether this has been mentioned or potentially already resolved, but in one of my playthroughs I had problems with encumbrance if I wildshaped into a smaller animal.
Of course it makes perfect sense that a raven or similar can't carry as much as a human. However, shuffling all my belongings into my friend's inventory is a bit cumbersome as well.
But probably all this has already been adressed.
Apart from that, I want to mention how much fun it is to play a Druid. Yes, he is no sorcerer
and I really have to point out how very, very sad, shocked and heartbroken I was that Larian has still not included the most important class in the game. But I understand that some people value boring fighters, nerdy wizards and even smelly druids more than the upper classes.
What was I going to say? Yes, well, the smelly Druid plays surprisingly funny & especially sneaking & jumping with your large polar bear right next to your friends in coop is fun. By the way, coop: Thanks for including LAN play, we don't have internet connection at the end of the world were we like to meet.
