Cooldowns Please

I was in a match of TfT when one of my matchups put me against a pyke with 2x spear of sojin. This allowed him to ult after 1 auto and then continue to spam this over and over stunning my entire team. Can we please have cooldowns put on abilities so this doesn't happen I understand you can't always get 2 spears of sojin, but I feel even 1 would make many champions able to spam like this.
