Vayne was 2/13

There really isn't much context here. 2/13 but had 100 more cs? She's fed then.

The 13 deaths only mean missed experience. If she was farming a solo Lane all mid game (as most vayne players do) and was killed every so often but was still getting consistent cs and xp, then her deaths only mean you or an ally got fed but didn't do anything with it.

Once you get to 6 items your kda doesn't matter at all.

If you get a vayne to 2/13, you need to keep her down and out. Respond to her every time she shows in a Lane and kill her 1v1. When i play Quinn top against a vayne adc, mid game i literally ult and go straight for her every time she shows on the map. Load up on free kills and keep vayne irrelevant for as long as possible (and get split push farm).

The biggest mistake you can make against a vayne is assuming you've done enough to make her irrelevant and give her the time to become relevant.

If she was 2/13 then got 6 items that means you guys failed to end it early. Having a game drag on for her to get 6 items is pretty much asking for it.

yeah, which one of the 50 threads did you copy this from?

Did you try to auto attack her? I hear that helps
