I've been having quite a bit of fun with Cho'Gath lately. nom-nom-nom
But it's hit or miss, I usually have a really good game or really bad, no in between. I think my biggest mistake is when starting a new game I forget he is not feed.
Only really played Miss Fortune and Cho'Gath, with the odd Ashe when MF gets picked. I picked up a bundle to a get around 20 champs so I can kinda play around with different characters and roles within the game. I went for the "Digital Collectors Pack" it seemed like the best value and had a bunch of champs I recognized. I'll give more and more champs a try as I get use to the game.
