then the problem is multiclassing, not the concetration on Hunter's mark.
Right now, with druid I see starting as 1st level cleric, then druid, picking heavy armor mastery plus moon druid. might be broken, might not.
I mean, you're not wrong, I've always hated a la carte multiclassing the way 5e and 3rd edition did it, but I've also realized that this was a fight I have lost, given the greater prominence (putting it right into each class write up) it's been given.
If nothing else, I am seeing some fixes, like tying class unique cantrips to leveling up with class levels. So no more dipping for a full Eldritch Blast anymore.
