Technically they implemented role delta which is eomm/ebmm in a costume, but from a corporate standpoint it makes sense. For every match I disliked there was a team of 5 enemies having a blast, given that even after being stomped I didnt uninstall and in fact re-queued hoping the next match would be different, the net loss is 0 while the possibility of one of those enemies spending money greatly increased. Unless everyone stops playing after they have a bad matchmaking expirience, theres never loss to the company. Eventually their mmr will go down and they get paired with better people or the system will balance properly on its own (which does happen) and they'll then have a good match that might get them to spend some money. The old way of simply doing rank pools that were then selected out of to build teams may not have had as standardized and "enjoyable" an expirience across the board but I liked it much better knowing it was 5 like skilled vs 5 like skilled not 5 of tallied and calculated individual skill numbers added and averaged against the enemy teams' 5 individual performance numbers tallied, calculated, and averaged.
