I have TEN chests. Guess how many keys I have. :)

I read somewhere if you play with people you get better odds of key frags

I have 27 fully assembled keys and 0 chests.

i have 15 keys and zero chests wanna swap?

Try ARAM. I've found that I'm more likely to get keys in ARAM than SR.

There's a weird skew to how the gameplay plays out to the different modes, thus the rating and resulting in potentially a different reward.

12 chests 0 keys here.
