I would say try a jungler. In terms of fun, Lee Sin is right up there imo. Nocturne is the only jungler who I find super fun (well Trundle I find fun for weird reasons but you could also go for him). Lee Sin is just fun to dick around with anyways. You could also try Cho'gath since he's a decent jungler and is all-around fun to play in lanes too. I love solo top Cho.
