http://gametactic.org/lol is created to make planning and sharing battle tactics quick and easy. Just press the blue button, share the link with friends and get started.

It basically is a collaborative whiteboard app where you and a few other people can get together and draw out your ideas on a map.

I originally designed it for world of tanks as wottactic. it was quite popular. So I decided to bring it to a few extra games.

So take a look, it's, give it a try. It's very fast and no registration required. And tell me what you think. Specifically, which LoL specific features do you think it needs ?
