There is a difference between bulky and obese and sufficient body fat hides muscle–think sumo wrestlers.
As for wilderness survival, that is not the lore of druids in Diablo/Sanctuary. They live in towers and villages. And depending on the climate, having a bit of bulk is a survival trait, as in cold climates it helps conserve body heat. Remember the D2:LoD cinematic? The climate is cold and the guy who confronts Baal is neither thin nor visibly muscular.
But bears really only put on the weight in for winter. More often bears are much thinner and may even be emaciated and look very thin such as Polar Bears in the winter when they haven’t had a meal in a month or more.
The Primalist (druid) model in Last Epoch’s game looks really well done.
Each class can only be one race, which is fine and it saves them a lot of development money.
The female necromancer and rogue models look good as well as the male mage.
It’s honestly killed my will to play this weekend for the most part. Once I found out I couldn’t make a normal looking Druid I just ended up playing another game all night. Gonna give it another try again today, but it’s comical watching her lumber around. Not even remotely accurate to how a wilderness survival expert would look at all.
I honestly don’t know what the point of locking body to class like this is. It’s the players who will create a character after their own fantasy, they should just make the entire game’s body types available for all classes, since it’s not whatever they thought a druid or a mage should look like that is relevant here. Build it around the players freedom of choice, not your own.
