check other topics, before making a new one: https://forum.4game.com/showthread.php?t=251 this was reported few times already. about your question, on-screen damage has been turned off on pts. on core it will be turned back on.
if everyone shall post lots of same threads and wont get answer, that doesn't they have to post even more threads about it, one is enought. its already reported week ago, this issue is well know.
innova know about the problem, they are quiet sure working on it, bumping this thread will not solve the problem and there is always a post concerning this problem. please be patient (i'm healer too and i also need to know how many heal i make but it's not blocking me so much to play)
