People who say players have "wasted" an ability would be better off saying nothing at all
If someone uses Flash to successfully escape a gank or score a kill, they didn't 'waste' it. In fact, it could be argued that having an ability available and not using it appropriately amounts to wasting it. The only reason people say 'X wasted Flash/ult' is to make themselves feel better, and it always comes off as sad and desperate. As if forcing your enemy to use an ability to kill you or run away rather than just using autos or walking away is a small victory. It isn't, League isn't that kind of game, cooldowns are short and abilities are used very frequently. So unless you mean to say that someone used an impactful ability without a purpose, stop saying they wasted it, you clowns.
