Toughest enemies

[Haven]

Colour coded Rage's, they're so annoying >_<. Dreamrunners can be annoying too, but only when you're fighting a group of enemies; on their own they're fine.

Tyrants and Butchers. The Dreamrunners can mix you up too but they aren't that hard to me.

The Dreamrunners get easier the more you pay attention to audio cues. I'd say Witches are the most annoying in any group.
