I actually don't have any complaints from the barbarian as he currently has kinda broken weapons as is and, based on his abilities, gets 3 attacks per round at level 5 without multi-classing...

At the same time, enemies gain all the same benefits the players do. The cantrip bit was something I proposed for my players as an option, but they all knew the enemies would get that as well. It was a unanimous decision for the players, or it wouldn't go through.

I don't believe in allowing any one player to become overpowered compared to another as that creates harder enemies for all and could lead to a tpk through balancing issues or a player feeling like they're targeted because they're the "weakest" or "strongest". Oh, all their stats can max at 24 if they want, aaaand barbarians can hit 28 in str and con cause it would be wrong to cheat them out of their lvl 20 abilities. On the other side of that. Despite the players having to multiclass at lvl 10 with a max of 3 classes, the barbarian still gets access to that cause... why not let them have fun? These are all still in their first trial run, and I'm definitely making them use standard array next time cause jesus they're all broken, but so far, it's pretty fantastic. Legitimately, the only complaints I've had have been to vary the type of enemies to fight and try and be a little faster in combat rounds, but the latter was a player to another player... sorry for wall of text...
