The second downed skill is bugged. Whenever I've tried to use it, the skill will go on cooldown straight after, and for some reason, gives me more downed health. It's not just me that has experienced this bug. I know a few other elementalists who have suffered at the hands of this, and as for me, it has been going on for a more than a week now and it's not fun.
