While the explication of Yoshi-P are nice and answer a number of things, they do nothing regarding two major problems affecting a huge number of players:

1) With current cap limits, you can't gear several jobs at once. While i get the motivation for the caps for a given job/role (prevent powerleveling to the extreme), it is still extremely detrimental to the game that one can not gear several job at once. The whole armory system is supposed to allow you to switch from one job to another in different dungeons/raids if oyu desire/it is needed for your comp. Here, you can NOT, at least in coil, as you have all but your main job locked at 70 (or all of them are gimped compared to the people you play with and focus on a single job). Why have a armory system in the first place ?

2) People that have cleared BC will have to wait 4 more months before getting a new challenge. The part about "go check pvp" is borderline insulting -- i could not care less about pvp, and i'm pretty sure a number of endgame raider feel the same. When i want pvp i go play starcraft, lol, dota, or a fps. I play mmo for the pve. Even though i don't have cleared coil yet, i feel the fact that we won't have anything harder to look forward to for 4 months distressing -- can't imagine what it's like for top FC of each server. And before you say that casual matters more, i beg you to reconsider. Casual and hardcore always have had a symbiosic relationship in online games. Most of the time one does not exist without the other, and if all the players that have cleared coil or are about to before 2.1 were to leave the game at once, i am pretty sure the net impact would be way beyond just these players.

Basically the "please look forward to pvp" line was a confirmation that no challenge is coming in 2.1, which is a recipe for disaster. Also, you don't have to clear coil to have >80 average ilvl by 2.1 (i mean if you clear turn 1 and 2 everyweek with your fc it is plenty enough), so you can expect to faceroll all new content the first week (because honestly, even for titan that gather so many complaints, once you get way overgeared you can steamroll him even if half your team are monkeys).
