Gamestop does. Funny story (at least to me) was when Ghostbusters the game was coming out. Gamestop had Dan Akroyd pre-record one of those messages. I honestly thought for a second Dan Akroyd was calling me for some contest I didn't know I won until about 10 seconds later. I still thought that was kind of neat though.
I think LoL has one of the worst communities I've seen in PC gaming right now. That's just my personal opinion based on every encounter I've had in that game. DOTA2 has been fine though I haven't played it nearly as much as LoL. I'd say go with DOTA2.
