Hey guys, thought i'd post a thread to inform you and Riot about the champions I believe should receive a visual upgrade, if you have any other suggestions, please leave them below. They are:
-Warwick
-Nasus
-Renekton
-Zilean
-Blitzcrank
-Galio

I am not sure if you are talking about splash screens or in game models, but if you are talking about splash screens, Galio just got a new one recently. Galio's new splash is also one of my favorites.

I agree with Nasus, though. His could use an update. They are updating all the old ones, so it will come in time.

sion's model and splash are horrendous

For one thing, Alistar really needs a run animation. When he moves fast he just looks stupid because he's basically just walking very quickly.
I completely agree than Sion needs a new splash, as does Nasus and Blitz, but I think Nasus' model is the worst of the three.
Also, Karma desperately needs a redesign and remodel.
