Frankly, at this point, I'm not sure how Larian could make them worse. These spells already bear the brunt of 5e nerfs to magic: re-saves every turn, concentration, removal by damage or expending actions, and a general inability to buff spell DCs - except by legendary items outside of normal leveling. On top of this, Larian has reduced durations, buffed enemy HP and sometimes saving throws, creating an environment that makes concentration much more difficult, allowed the removal of conditions via mundane actions like shove and jump, and in some cases made their areas easily destructible.
One would think they might understand that these are actually class features they're toying with, but alas. Given their fundamental design has indirectly nerfed most of them, their direct nerfs seem almost hilariously vicious.
