So i really enjoy top lane, and wanted some suggestions on who i should try playing next.

I enjoy the tanky dps type champions, although i dont object to assassins or pure tank.

I really love Olaf's play style, as well as Malphite and to a lesser extent Jax.

ive tried Singed and thought he was ok, not by favorite.
Also tried Cho'gath, didnt really like him


Im thinking about Elise, Akali or Xin Zhao.

Any comments on those 3, or any other champions you think i may enjoy playing top?

Xin and Elise fit your tanky meta, Xin is much easier to understand and master though.. Expect to play a lot more games to get Elise down.

Both are also excellent junglers, so you really can't lose.

i would play garen or singed. singed is more of a "troll" charachter in the fact that you dont play him the way you would play other champions.

I'd recommend either Garen or Shen. Garen if you want deceptively good damage and still be a tank, and Shen if you want to be an all-out tank that has incredible team play possibilities.
