When ive joined the chinese server for a giggle, ive usually noticed how its very clan stack based, i saw 90% of the population belonging to either one of 3 massive clans. This wouldve been amazing if it was ever to be true on eu servers, allthough we did have stacks it was never to the point of chinese scales. I think not only does it promote teamwork being in a clan, but also forms tighter bonds and keeps people playing for longer times. Unfortunately it was always shunned upon, being in a major clan, its only for bannerstacking and multipliers not for actually wanting to enhance the experience but only for minmaxing. Some of my best experiences were definitely when a large merc stack was rolling, and on byz teamspeak we would try to round up all the people we could to get a counterstack going, similar to the feel of a tournament game but with an extra chaotic feel where the other randomers on our team would sometimes force us to adapt.. ah nostalgia.
This could very well be the case in CH aswell, maybe they hate on stacks just as much, i wouldnt know i cant understand a word they are saying.
