2) You do realize that pushing the content earlier is actually BETTER for casuals. Having more options for gear, and them getting into LFR, will allow them to do regular MV, and start the progression chain into Heroic MV and normal HoF.
Delaying it only will make them realize they don't want to wait to play a game they paid for and will quit after their month sub is up.
So good job on doing it for their sake.
3) What happened to the whole faster content with MoP? There has been less content across the board with the release of MoP.
Vanilla was what... 8 content patches? BC was 4. ICC... don't be fooled by only having 3.3.something... was actually 6 content patches. 3.1, 3.3, and 3.5 were all content patches.
Cata had 4. Only 3 were raids, but they opened with 3 raids, and had big plans for Abyssal Maw that got scrapped.
So... a month in... and 6 bosses. And really nothing else to do at 90. And 6 bosses in a raid, that really doesn't make a whole lot of sense. Why are we even in MV in the first place?
