if your having problems with switchers use higashi the master with mind readers chalice his intercepts are a free chance to do 75 damage and fully restore energy
hot runner why did you other working that out? anyway Arcane is fun but I think you should be able to walk through your allies, getting trappedbetween your ally and an enemy when only equipped with a bow sucks
