Irelia
So I know she has a stun if she is at lower health.... but apparently it means lower percentage health as I just had an irelia who had like 3k health stun me when she was at 1500 and I had 1000 total health... yeah seems balanced. oh and a 2.5 second stun yeah seems balanced specially as she then used her free life steal to heal to full while I was stunned. yep nothing op there.
