I was playing against a void night and he used his dark cloud form for 90% of the match. It Was impossible as a gladiator to engage my oppent when they were invincible. They were able to switch in and out of that form with no cool down. Please put a cool down on it and give it a shorter duration. I have to blow evades because of surprise attacks from that form and they don't have to blow any evades. Maybe give it the same run time as charging thrust and a longer cool down.
