Personally, I'm still on the edge of quitting at the expansion launch due to my fear of having the same, exact cycle of patches that we have so far and I'm probably (hopefully?) not the only one with this fear.

ARR was a relaunch, it was ok to play safe, but I was utterly disappointed with HW - especially the first 6 months where we had only 2 dungeons to run with, one of them being one of the worst ever made - and no relic to work for. For one thing I'll definitely wait a few months when SB is released to see how it is "content wise" as I don't want to risk ending up with running the same 2 dungeons over and over and over like I did in ARR (remember, relaunch) and HW (an expansion), but if I start seeing patch 4.1 with the same exact stuff that 2.1 and 3.1 had, I'll probably call it quits for good.
