The only other thing I see is the idea of enemies needing more variance in defenses but that needs its own topic, this one is about CC.
It ends up being about the same topic since CC chaining is effected by defenses.
Recall my point that changing indivual enemy defenses would be more work and doesn't solve the issues of player defense once the AI is smarter.
Thus, the more general and easier solution is just to evolve the current defense mechanics
