Why it would be more active if anyone is forced to be in only one of 2 / 4 clans than now? If someone isnt playing cm right now I am sure he wouldnt play when there are only 2 clans anyway (its just name of a clan and nothing else because there is no difference u play vs clan A or vs Clan B , C and D).
Because there are usually about 20 people online and never are there two from two individual clans online.
If there were two clubs, and all those who are interested in clan matches joined one of them, there would by theory be a much higher change of 2v2 ranked happening.
Pretty stupid question no offense lol
