ok take the example of Paragon. when they downed Synestra despite how buggy it was. they were pretty happy with how the raid progession toook place and were happy to from from burnouts to 1 raid day a week. and paragon did it b4 1% of wow population even SAW synestra...and i think that its still that case. look @ how many guilds have 1/13 heroic content yet alone 12/12 reg. Having 4.1 with ZA and ZG appeals to - this may shock you - 99% of wow population. This will server as a buffer to all types of players. Hardcores will have something to do to prepare for Firelands and update few BiS and for the rest of us it will help us with GS to continue clear content. on my server the top guild is only 4/13 heroic and im sure that it is close for a vast majority of players.
aside from that you are also making the same generalization mistake you accuse Ghostcrawler making. "Speaking for myself and many others within this category" does the many others are jsut your guildmates can u actually atest to other 50+ guilds feel the same way?
Bottom line is that it is smart to keep firelands till 4.2 because of howmany guilds have yet see the content. and Blizz would rather cater to the majoirty of its subscribers than a dozen of so guilds. If you are bored then you have choice..take a break, roll alts or find another game to play.
