This seemed like a glacial shift but more recently it has been absolutely tectonic in its speed. A real game changer. Before the patch it was 'all L/CSM all the time'. And then suddenly, literally over night ever since the patch 1.8.0 landed it went from 'L/CSM only treehouse club bromance' that went on before the patch to a bit of every faction most of the time. This is a good thing! because it means more Xenos matches, more variety and more fun! I have a few ideas what might have caused it but I'm interested to find out what sense the community has about what might have caused this shift so we can potentially continue the momentum as it doesn't seem like all that much has changed. -edit- Post update; We're seeing more variety in factions - more Xenos - and less of a L/CSM sausage fest, because of some wide sweeping much needed nerfs. Unfortunately this is not as true as it could be for Eldar because one of their most infamously hated tools was buffed when it really didn't need to be so there is still a lot of match dodging going on there because of that. That^ is a good example that sometimes a nerf is in the benefit of all involved, even the people on the receiving end. But getting back to the real cause of the shift - On a small scale when a class or weapon takes another class or weapons job due to over performance, variety suffers within that weapon or class range and as a result all other classes and weapons suffer and a nerf is required to bring that variety back. So on a much larger scale when a pair of factions and certain weapon within those factions take all other factions jobs due to over performance the entire game loses variety and becomes stale and a nerf is required to bring that variety back.
