I tried today playing with Cho'Gath.
In my last match (against AI) I got 4 kills, 1 deaths and 24 assists. Is it a good score or I should get more kills?
It's a pretty good score. However keep in mind that kills don't automatically win games. When playing PvP having the most kills doesn't mean you contributed the most =)
No, but 24 assist does
You did good actually. Cho should be letting his carries grab kills. However that by no means mean you can't get a couple yourself.
