Yeah I imagine as much. Even in PVE, WoW is a somewhat competitivie game, where players will want what is true-and-tested. Look at GS for example, raids that I think could be completed with a 4.5-4.8gs are being lead by players ho ask 5k-5.2k+.
My casual-*** is not going to change anything about the meta, and in the end it is fine. I don't care that much, I just want to play.
