Crowd control spells are too heavily nerfed. There are three major nerfs.

1) The durations are reduced from 10 turns to 2 turns.
2) Enemies perform unarmed attacks to wake each other up from CC.
3) Enemies get to make their saving throw at the beginning of their turn, rather than the end, counter to DnD rules.

As a fourth honorable mention, we have enemies targeting casters on tactician mode, breaking their concentration.

This is bad for CC-focused casters in general but especially bad for bards, who don't really have other options until they get magical secrets at level 10.

It makes Confusion especially useless, because enemies must fail two saving throws before having a chance to act confused. Unlike most other spells, it does nothing in the interim between casting it and their first turn (you don't get advantage when attacking them, for example).

I'm not sure why Larian decided these spells needed such heavy rebalancing, but they need to revisit it.
