Having a vayne in your team is the worst experience ever
You already know what is going to happen before the game even started.
The game will be 4v5 for the first 40 minute.
The enemy adc is basically destined to be fed out of lane.
Don't even think about sieging early game, you don't have an adc.
You know you will hear "an ally has been slain" when the Vayne ignore teammates' ping and overextends to the enemy bot outter with her outter down.
Even after the Vayne hit the power spike, due to the FOTM abusers having horrible mechanic and knowledge abut the champion they probably end up fuxking up anyways.
Oh did I even mention about toxicity?
Sigh, end rant.
