Why don’t they give mega knight a little nerf?

Like genuinely, he’s a bandit on steroids, what I was thinking was a cooldown on his jump, like 3 seconds before he can jump again or if you spawn a unit on him it cancels the jump and attacks that one yk? Cause ts is getting rediculous when my lvl 13 cards are getting rolled by a lvl 16 mega knight every single match.
