How do you beat varus mid

Buy boots, move around, win.

Cmon homie...he is easy to deal with.

should do ok against him. He can match Varus in range and waveclear, and his passive allows him to out-sustain Varus in terms of mana, giving you a sizable advantage before he gets Tear.

Hello summoner!

A helpful tip is to keep your mouse near your champion model. The idea is that if your cursor is just a few pixels away from your champ and you need to juke right, it only takes a tiny mouse movement to do that. Compare that with someone who keeps their cursor all the way on the left end of the screen and has to juke right, they'll have to move their mouse a lot further and take more time to respond to a skillshot.

You can also issue more precise pathing comands this way. I still think this isn't very important though. If your senistivity isn't super low you can easily click places in pretty much the same time with a few ms difference. Dodging is more about predicting or paying close attention to enemy champion animations in my opinion.

Varus q's has a key animation windup where he draws his bow back, pay attention to this and try and predict where he will fire.

An example of this animation on one of his skins: http://1.bp.blogspot.com/-cQHPbAOnLRc/UyntrmuQGoI/AAAAAAAANek/ADw7MigDiJo/s1600/v666.jpg

Hope that helps!
