Why pro 10 mans always choose to use custom lobby to play? isn't it possible for them to just 5 stacks ranked and queue at the same time? seeing almost no one do 5 stacks radiants, surely it's a guarantee they'll end up on same lobby.
or is 5 stacks radiants is not even possible in the first place?
if they do the 10 mans in ranked lobby, i believe it should be more entertaining because there's RR at stake unlike custom lobby where there's nothing at stake.
