Despite some bugs, and it isn't due to being druid, I am enjoying the class. I am not sure why barkskin is considered a concentration spell, but I guess it changed in 5E mechanics would be my guess. Not sure if Natural Armor is still a thing anymore for AC bonuses. It used to just give you like a set armor increase based on the caster level. I guess its just a straight up AC 17 now. So if that is the 5E rules for the spell now just don't be a druid caster fighting toe to toe with people. However, I have noticed that casters seem to be more sturdier when it comes to concentration checks. That just may be to me getting luckier on the RNG, but helps nonetheless. The class does give me hope though that if they spent this much time at getting the druid to work well I think Paladin and other caster classes are going to be great as well.
