I used my skill reset books today to find out the cool down and cast time on Super healing wave. at level 4 you'll get a heal bout 4.9k LP (wt RP u'll get bout 6.7k healing ), wt a 1.5sec cast time and a 9.5sec cool down and used up bout 1.1k EP. I still prefer the ' Healing Wave' skill where i can spam, wt a 2sec cooldown, 0 cast time, gets bout a 3.5k healing (wt RP u'll get bout 4.8k healing ) and and used up only bout 700 EP. Well, as i said up to u. It's still a good skill if u are out of healing skills. Good luck have fun.
