I'd like to keep the duration 30seconds but I do see your point. How about moving it away from the ticks and it to the cast of medica II. It will really only be used once every 30seconds so the proc chance needs to be higher than the average 15%. On that note if its per cast of medica II then reducing duration to 15seconds isn't a bad trade off ether for more procs. Also now that it is explained about the spaming of cure II and now that isn't a think sharing the proc on cure I is a good idea but what could we do for cure II?

How about giving cure II an additional effect to increase the chance to proc freecure on cure I? I'll put it up to my original post and see what people think!
