You can have mastery points on a joke mode of ARAM but not on normal ARAM and TT...
I really don't get riot sometimes, is it so hard to have a key feature in the other modes? Especially now that we have hextech crafting, why don't you want the TT and ARAM community money, do you think it's filthy money or something? Like seriously how hard can it be to implement mastery points and chests on other modes? Then again you removed a 4 year old mode because you couldn't be bothered to waste 0,1% of the money you make per year on it, so i dunno why i still get surprised by this point.
PS:Dynamic queue is also a joke in normal games , 90% premades is a lot of fun, and i don't miss TB at all, keep up the good work.
