a way to give gnar a small but impactfull buff ( i think)

I've been playing Gnar for a long time now, but I always played him as a lane bully and split pusher instead of an amazing teamfighter ( mostly because the ult is hard to hit, and the team doesn't follow up :D). i was thinking how maybe giving him a small buff ( so he wont get too strong again) by increasing his jump range (E) when he is transforming into mega , and only then this will make his ult easier too hit.

i'd like to hear other people there thoughts on this.
