fiora's ult is really good for tower diving

Pantheon he will grand teabag you and block the turret W you and block the turret again and then if you are still alive he will HSS while tanking the last few shots

Lee Sin is an absolutely amazing tower diver if you have a ward/minion/ally handy and your ult up.

Revived thread? 'Kay.

1. Garen (speed boost and ult)
2. Tryn (ult and e)
3. Viktor (long ranged lazor, slow and stun, shield, and nuke that silences)

The best people to defend against dives...

1. Shen (with heal and exhaust I killed a full health vayne when I was at 1/3)
2. Tryn (Dat Ult)
3. Any ADC with a Soraka

Defend?
Kayle & Karma(the number of heals, slows, and shields is great for trapping)
