User blog comment:M.Davidz/Talking About Varus and His Current Status ( Rework )/@comment-25003900-20141121151344

As was already said below Varu's issues are with the fact that he has to deal with extremely mobile champions and every one of his abilities aside from the on hit effects of W, are skill shots. Varus' E is intended to try and help you hit those skillshots, which doesn't work well because it's applied at a short range, and the radius of the slow isn't very large.

Varus certainly isn't weak, he's just not particularly strong against most of the champions he has to deal with in the laning phase. Look at it this way. Popular ADCs: Lucian has a dash, Vayne has tumble(technically a dash), Caitlyn has her net(also technically a dash), Tristana has rocket jump, Ezreal has Arcane Shift(essentially flash), Kalista basically dashes after each basic attack. It's no surprise that he has a very difficult time in the laning phase and through the rest of the game when you realize everything that detonates stacks is a skill shot.

The good news is that he's brilliant in teamfights. His ultimate can potentially snare an entire team and make them easy pickings for every skillshot your team has, it also detonates stacks, does good damage. He can build stacks easily and he's almost guaranteed to detonate them when he fires his Q into the group. His passive makes him beyond lethal when you kill anything during the teamfight. Small bump from minions, use it on a champion to get the big bump and you obliterate their health bars. Add good lifesteal in there and you can lifesteal through Vel'koz's ult (I've done it several times.).

He's a solid champion, that just isn't phenominal until the grouping starts.
