Gnars rage meter needs to refill faster/have its CD reduced after transformation

As a heavy Gnar player I respectfully disagree. If the rage meter filled faster it would be harder to manage for team fights, as one minion wave would easily proc the passive. Further, in lane or in team fights, Gnar generally wants to initiate when he is mega. However, mini Gnar is a really tool for kiting, chasing down enemies to finish off a kill or to simply disengage (especially if you build Frozen Mallet). Lowering the Cd would risk Gnar's passive procing in a disadvantageous way during this portion. Not to mention, there is the added issue where in extended team fights, he could Gnar out twice too easily. It is still possible to do so in really extended fights but with the CD lowered, you could easily see Mega-Gnar twice, which in my opinion is an advantage to Gnar, as he has CC in mega Gnar and team fights really well then. I think it's in a perfectly fine state tbh.
