It's ridiculous nerf that takes the class from "at the powerful end", but not even OP, because it's basically got one trick (it's certainly not up at full caster levels of full-spectrum power), to "mediocre", whilst particularly removing the one thing its famous for, and further makes incompatible with anything at all that uses Bonus Actions, which is like, a significant fraction of the mechanics in the game. Further, it means they can never Smite outside their own turn - a really boneheaded mistake WotC made with Rogues in early 2024, got shouted at for, and had to fix because it was such a stupid thing to do. So you can get a great Crit on OA or whatever and can't do anything with it.
It's just completely unnecessary, especially in the context of literally all Full Casters being improved by margins from the small to the huge - hopefully some of that will get dialled back, but if they went live with the most recent packet, Full Casters would, universally (I think Clerics, I've paid least attention to them - but definitely all the others) gain power significantly, ridiculously so with Wizards and the insane "Memorize Spell" (i.e. "Dominate all non-combat situations and free up all memorization slots for combat spells"). It's just bad joke level of balancing. If this was a videogame they'd literally never hear the end of it - and indeed if they make the 3D VTT, they will never hear the end of it.
