ARAM snowball cooldown is too low.
In the spirit of Riot's year of "Strategic Decision Making" and the on-set of the the ARAM snowball it has become apparent that there is zero decision making in the use of this summoner.
People are just randomly flinging out snowballs because there is almost no cooldown on them. You don't even need to hit your target because if you hit someone else, you are usually close enough to cc the proper target. I have seen people use them to cs, because the cooldown is that low.
TLDR: Snowball cooldown is ridiculous, needs to be increased.
