Larger ARAM dodge penalties
The dodge penalties for ARAM are the same as for Rift, and this does not reflect the different natures of the two modes champ selects: in Rift you need a coherent team with champions that make sense in their roles, so dodging to avoid a troll every once in a while is ok, the penalty reflects that. ARAM is an entirely different matter. The same penalty suggests that it is ok to dodge because you dislike the champion you got, which is obviously not the case, a player shouldn't be able to ruin the game for 7-10 people satisfied with the champion they got. A good solution is to have an ARAM only dodge penalty that only affects the ARAM queue. This would be 1 hour on the first dodge, 6 on the second and beyond. This way the people who dodge for the only reason it is ok to dodge an ARAM game, which is having IRL stuff to do and thus having to leave, would still be alright since they are leaving anyway, however people dodging to avoid playing a particular champion would not be able to ruin games for everyone else.
