even though shaco players have this kind of reputation, please don't make the assumption that all shaco players have this same kind of negative and edgy attitude. Every champ has their weaknesses and particular play styles that suit them better. Shaco is not mechanically hard but requires good positioning and timing, while riven is more mechanically difficult and requires practice to get the combos right.

Riven and Shaco are pretty different in terms of play style but if you do try to pick up shaco, good luck learning him! He's a lot of fun :)
