That poll is extremely biased with the obvious answer the OP wants you to gravitate towards is yes. I choose No for a multitude or reasons and not a single one was because "I want new content ASAP ".
We can match pros and cons to delaying the xpac or not as well:
Pros to releasing next month:
Helps retention from a really bad xpac
More time at this point will at best see marginal improvement
Able to see problems in a live environment instead of a beta one with limited playerbase
More content(i guess ill use your excuse here too)
Cons to releasing next month:
Might miss some small things they could of caught in a beta environment
Its ready when its ready can sometimes be long or sometimes short. If its ready i do not see any reason to delay it and from what ive seen to support this:
They've got class design locked down the best they can in a beta environment
They only have tuning left(which doesnt take long at all)
The zones are done
The content is made and complete
The systems are what they wanted and complete
So objectively speaking what would delaying it actually do for the game? If it releases with problem(which it most certainly will) how would an extended Beta have fixed them.
the problem with BFA was that feedback was ignored because of the time schedule and in that case i would of absolutely agreed with you but since they taken things away and have allowed more time this time around with Shadowlands as well as listening to feedback i feel they actually have pushed it back quite a bit(getting a oct release instead of an august release.)
