For the love of god, please get rid of snowball in ARAM.
Tanky teams are ungodly broken, and there is nothing that can be done to counter them. Even more so, you have entire teams just leaping across the map.
NO ONE should have that kind of engage power. If you are engaging, you should have to WORK FOR IT!
I don't care how many times I am told to "simply dodge them," all it takes is one to actually land. I absolutely abhor ARAM ever since they added this pestilence into this game mode. It has single handedly decimated the game mode in general, and IMO it is borderline unplayable. Remove this joke of an ability!
