Just witnessed late game allied vayne lifesteal and it made me sick

her early game was average and team was behind most of the game but we started winning some fights and at the end we were at their nexus but all died expect vayne with like 40% health, they kept spawning in ones and 2's she was lifestealing 300+ hp per crit with almost 2.0 attack speed while kiting for days, killed 4 people solo and took nexus.

30% lifesteal vayne is outta control.
