^Yeah... Twice as fast... That means the opp carry is on a 1.25 AS while vayne is on 2.5

If you think about it, if a standard carry takes 2 hits to shut down an opp carry that equates to around 1.75 seconds?

However, AS vayne would take 6 hits with a AS of 2.5... which means 2.4 seconds. You can say theres only a small difference, but that small difference can really judge whether or not other ppl can burst u down, etc.
