User blog comment:TFCrafter/What champs should I play?/@comment-27802145-20160419151104

Jhin and Rengar come into mind when I try to come up with champions with lots of damage and a low skill floor (ie. minimum amount of skill required to play the champion at the expected level).

Any of the juggernauts also (Garen, Darius, Skarner), excluding Mordekaiser, may bear you some good results.

If you're not planning on using any money on RP though, and thus are relying on purely IP for purchasing champions, especially consider the following: Poppy, Sion, Garen, Master Yi, Shen, and Volibear.

Generally, you don't want to go near supports or ADCs pre-30. Or at least, that's what I did. I think people learn the core aspects of the game a lot faster when they play mid lane or jungle.
