Hello there, I was wondering why don't we have exp for all game modes but only for Summoner's Rift. Let's say that Dominion was rarely played, now imagine how less played it is after they "boosted" Summoner's Rift. I consider that no matter what mode you play, you are playing champions and you should get experience. What logic is right now? What I mean in Champion exp
P.S. 
Fucking op xD
Evidently it's because Riot hasn't come up with post-match grading algorithms for the rest of the maps. I'm not sure why that feature is absolutely vital for Champion Mastery or why they couldn't just (temporarily) award experience based on win/loss and game time (possibly including the same modifier as the Dominion Bonus IP reward), but that's the reason we got for ARAM.
Upvoted because vayne op.
Kidding, every map gives EXP and the other modes tend to be a lot less frustrating.
I assumed at first it was because they were rolling it out in just one to see if it was balanced the way they wanted it. At this point though I see no reason they shouldn't add it to everything else as well (maybe excluding custom games and co-op vs. AI)
