I play Vi alot and think she is a really strong climbing champion. Some things to think about is to try to always ult on the enemys best carry in the games. It will help your team very much in team fights. Try to come and make your gank when the enemy lane is pushing then you can knock them back with ur Q. A strong tips when u use E is to do one basic attack and then use E then one more basic then E agien. Try to ward so much you can in both your and the enemy jungle, it will help the other lanes controll better were the enemy jungle is.
