Ranked 5's and disconnect

Can we remove the auto disconnect from a ranked 5's.... like the punishment.. i walked into these matches knowing the people i am playing with..

Story.. doing ranked 5's, one member had to leave.. game won.. he got marked as AFK. can we not have that.. i understand if it was solo que... then you are messing with 3-4 other people.. but in a ranked 5's we picked our team mates.. and we should suffer and reap the benefits of their actions..

please correct this.. i am going to assume its either an oversight .. or a bug..

basically: i am asking for auto DC detection on ranked 5's be removed.

who knows .. maybe a 4v5 is how my team wants to win.. we shouldnt punish a member for playing the strategy.
