I've been hunting Lang swamp trolls in Test. Their Arc Light spell never works on me until my fatigue or vitality are around 85% or less in either category. At which point their spells seem to always work and I get sent into a downward spiral of semi stun lock. Feels a little out of whack, so I am giving you the feedback. They appraise as slightly less skilled opponents for me. I can counter this by BOBbing often to recover fatigue but the small hits can sometimes add up enough to make me vulnerable again. Also with a bunch of mini wounds the regular attacks also stun me. I can spend more time stunned waiting for my turn than anything else. With my balance tanked, I'm unable to be offensive.
Maybe if this happened at a lower percentage it'd be less of a headache and more fun to work through. Thank you for reading and hope this helps give you some perspective from my point of view in test.
