Wouldn't it be better if they released 5mans a week before the LFR, then normal a week before the heroic (as it is now actually)? I may not need loot from 5mans but it might be more fun. Also LFR might be a chance for raiders that do not PTR to see the bosses once in a nerfed way so they know at least the 'room'. If LFR was full as well of course.
Then again concerning LFR one might think it's an abomination to not use normal and heroic mode before killing Deathwing so that could stay together with those or even a week later as it is now.
Hrm, ye, as I said it initially but with LFR going AFTER the normal mode might be cool, as it is almost now. At least the 5mans to be earlier.
I'm not saying to release the patch later, but as it was earlier so the 5mans are first.
Then again one might say they don't want people that just now levelled in 5mans to be ready for raiding.
