So why wasn't Magma Chambers released?
I'm pretty sure a lot of people would love a 1v1 map (With ranked implemented) I mean it could be a 5v5 map but that would be too similar to Howling Abyss and the map was so short it would be so hard to end (People going to base and healing up constantly) If it was released it would be cool to have something like a harder version of Dragon with a buff somewhere between Baron buff and Dragon buffs strength,
I don't know though it's just my opinion and I never saw the explanation for why it was gotten rid of but it would be a cool replacement for Dominion (If ever replaced)
