This skill is so under powered that it is useless. At lv5 it is the same as useing a small health poton. The cool down time is way out in the twilight zone. Needless to say this needs work. What they need to do is give skill the same stats as the first dragon commander you meet in broken vally. Recover 1000 HP cool down time 5 sec. Only then will this skill be useable.
