I'm not saying do that to current tier. I agree you still need some sort of loot treadmill blue balls for the last tier. But all the previous tiers that are gonna be mandatory to get to that point and 3 times more difficult to get through then they are now. The point of the 5 man dungeons were to introduce RP elements leading into the final raid and as means to catch up to your friends gearwise. Without the new dungeons you are left with only one method of catching up to your friends and thats LFR. However anyone that resubs and realizes its gonna take MONTHS to get were their friends are is just gonna quit once their gametime expires as is more preferable to just wait until a new xpac at that point.
