It’s not free if he has to throw himself into 6 enemies after standing still in front of them for 1.4 seconds
Only has 250 health. He gets more by landing his abilities, so he should only have tank like health after a team fight he won.
As for his low cooldowns, there are two 6 second ones and one 4 second one. Without these he can’t do anything. Even with the sixes being a second longer he was terrible.
