Galio!
Just noticing Galio is getting dated and may be up for a rework in the near future. Its odd to me that Galio is always in the air, yet has no mobility in his kit. I think it would great if Galio had an ability skillshot that allowed him to dive similar to Aatrox. In order to preserve his identity as a strong counter mage tank, require his dive to have to charge by taking magic damage over time. A new updated animation could show on his model so enemies and allies know when Galio is fully charged and ready to dive in for a team ult.
Just an interesting thought! Feel free to add your two cents!
Edit: Galio's E does provide mobility as noted below. No harm meant by my post... just thought it would fit his character design nicely and that I would contribute my ideas!
