Let's be real, most of the quitters and streamers will be back next expansion when all the hype comes in. That's why I can't take all these streamers serious (Asmongold, Preach, Bellullar, etc.) when they say they are most likely done with WoW. We all know when the next expansion cinematic comes and the hype is off the charts they will all come crawling back again. They cannot escape the WoW cycle.
This is not only streamers but majority of the quitters as well. I have seen this happen too many times to count.
