Gnar Gneeds Some Love

Ok, so recently I picked up Gnar and Fiora when i had some extra money, and I started playing them. I found them both extremely fun, but I felt like Gnar was more so. Now, traditionally, I am a mid main, but for once I found myself attracted to a top laner. I mean, who couldn't love Gnar??? He's adorable! So I watched a crap ton of videos on him, and on one of them, I found out how the rage mechanic came about as a way to keep him from becoming broken like other transformation characters ( I'm looking at you, ) . But, while I was playing him, I realized this wasn't a great balance at all! Now, I know that not every character can be the best in its lane, after all, there can only be one best, but at the same time, I felt like Gnar's power was... lackluster. The point of the Rage mechanic was to restrict the power of being able to switch between two forms, but I think the real issue with transformation characters isn't the transformations, but the forms themselves. I mean, sure, Udyr being able to suddenly gain a crap ton of movement speed at will is an issue, but I think the real issue is that freaking movement speed bonus itself. When I look at Gnar, I find that neither form is good enough to warrant the split. Mini Gnar isn't tanky, and he doesn't have any more damage, in fact, I find both forms very weak in the damage compartment. Mega Gnar is slow, and while he has some damage buffing, it doesn't matter because he's too slow to really do a crap ton of damage (unless you're fed, but I mean, in general). Of course, Mega Gnar is meant to be a tank, but here's the kicker: it doesn't last long enough to matter. Most of the time, as Mega gnar, you go in, ult, maybe stun, and then leave. Great, not too overpowered, right? Yet, Sion can do almost the exact same thing, except, he doesn't have to worry about changing forms, his knockup is low cool down, his R actually does a ton of damage, his E gives him poke, and he is WAY TANKIER and has WAAAAY more damage. I guess what I'm trying to say is, Gnar just can't compare to most top laners. What he can do, someone else can do better, and with less need for timing. Kinda like Urgot was for a while. I personally think needs a buff. Of course, I know that Yorick's rework is next on the table, but I'm just saying maybe increase the difference between Mini-gnar as damage and Mega-gnar as tank with some stat changes?

(Oh, and needs an updated model. He looks more like a murloc than a yordle and I think that model is kinda old.)
