I have a druid and it's not bugged for me that way. 2d10 yes, but I'm at times not getting the extra damage at start of enemy turn. If it moves, it doesn't get hit by moonbeam again. Often, anyway. Also, If you move moonbeam, you lose any other opportunity to attack. Before this patch it was a solid 4d10, moveable in wild shape. It feels nerved to hell. It wasn't a real 4d10 because it saves half the time, but it could be alright for a half tank/half caster.
The only way to go is Flame Blade, (18) Flame Blade again (18) with Item Bonus Action + normal melee attack (11). If flameblade deigned to work properly, that is. The averages are lower, but it evens out to hitting with one spell that doesn't suck.
