Played a matched game with a friend where the rest of our team were assholes. I played as Veigar, and I admittedly didn't do super good (laned against Ashe. the harass, it burned) Our chat was literally full of "Shaco Nunu noob" and "veigar terrible go back to AI" it was a circlejerk of hate where everyone but me and my friend was an ass. We lost, 'course. The enemy team was a better than us, and the fighting didn't help at all. Seriously the hate started in the first two minutes where I was called a retard for not buying a Doran's ring.
And that brings me to the next point; how to get better as Veigar, or really just generally? Practice practice and play, I'd assume.
As well, how to lane against a harass heavy champ like Ashe? AS far as I know, stay behind minions to block her volley, but I found that it was easy for her to run forward, get an autoattack in, and I could do nothing.
