Hi there, thanks for playing and for taking the time to write down your feedback.
Agree with the ranger being the weaker class at the moment, the fact that the boss can cleanse itself from physical conditions is also another factor that makes the ranger less effective. We'll definitively give the ranger some love with the next patch.
About distraction, it's indeed a bit of a bittersweet pick as of now. We'll likely need to think about how we approach this kind of modifiers design-wise Might make some of the skill modifiers toggle-able and see how it goes.
