a 4 second fear is op, the longest CC there is in the GAME is a full length Ashe arrow, and that is only 3.5 seconds. Maybe make it 1/2/3 seconds, and, even though they can be awakened, a 6 second sleep is a bit long. That is the main reason there aren't sleeps in the game already, their pretty hard to balance, because if your teammates don't realize you JUST put someone to sleep, then it was a wasted CC, but if your team is smart, it's op.
