After all these years
Champion hit boxes are still invisible, skins have not been fixed for horrible animations (like I-Blitzcrank), and abilities still read just numbers without telling you what they are from.
Fixing skins and champ hit box issues would help break a lot of the toxic things that go around in this game. You know that magnet Thresh hook that just hit you? Maybe it wouldn't seem so magnetic if you could see your own hit box or even the enemy's. Some skins even make it worse by blurring bad animations even more.
Abilities not showing their ratios while not being visible from outside of the game makes a huge burden of knowledge on the player. Sure you know something has AP scaling but for all you know it has a .1 scaling and not something like 1.0.
I mean I feel like all these changes are quite simple and would improve the game a lot.
