Riven is a fighter/assassin she is a very strong duelist if you use her spells correctly. Riven also snowballs really hard if u get a lead in the early game. She is really fun to play and easy to pick up but it takes a little more to actually master her. If you are looking for an easy to pick up and strong top laner i recommend riven.

Farming with Riven is really cool and easy, she has so much AOE damage that by 20 minutes you should have 100+ farm if you are not roaming.
