Let Gnar have control over his transformation like Jayce and Elise
Instead of managing a rage bar, I would appreciate if Gnar were instead a completely resourceless champion and his transformation mechanic functioned like Jayce and Elise where you can switch on the fly.
This would make Gnar more reliable and buff him appropriately in my opinion. It is incredibly distressing to be capitalized on in his smaller form by bruisers and have no agency over it.
