Stomping meta-slaves is satisfying and yet equally disappointing
There is nothing more fun that ruining some no-skill sheep abusing one of the cancerous tumors Riot put into place, but at the same time it sucks knowing that the only reason you beat them was because the person playing those champs was a dribbling vegetable.
It doesn't feel nearly as good once you realize that had the enemy using them had a working brain they'd have just steamrolled you regardless thanks to their overtuned thoughtless kits.
