You know they have like over 10 million players right? Hell when I have needed it I have never had a bad time with support of their game. ((like awhile back my old laptops graphics card crapped out, I had no idea. Had support try and help me figure what was going on, took awhile but eventually we figured it out.)) so maybe you have had a different experinece with it but I dunno.

Not to mnetion all the literal Red Posts on the forums and the fact that they do AMAs for every new champ before they come out. Reading stuff on Surrender at 20 let's you know just how active they are. Other companies don't do squat compared to Riot.

I've also found their support to be very friendly, even if they can't solve the problem they offer some way to compensate.
