I agree with the sentiment in this thread, but I wish people would stop pointing at CT as though it's supposed to be the next bit of content to add on after BC when it's not, was never meant to be, and was never presented as such.
Anyone who's already got the iLvl 90 gear and has no use for what CT has to offer, essentially just jumped that particular step in the gear climb. The step is currently missing, so there's currently two options: Grind AK/WP for Myth tomes to make that jump from AK gear to iLvl 90 gear, or stop at Darklight/Relic and wait for 2.1.
Some of the people who simply jumped the gap in the stairs (which I'm not critcisizing in the least, obviously; there's no step there, so there's no choice if you wish to proceed further) seem to look at CT and think SE's offering it as next step up, when it all it's ever really meant to be at this stage is the missing step that's been jumped over to get to where they are now.
True, the only 'new' content in 2.1 sounds to be harder mode versions of pre-existing content, which is a reasonable disappointment/complaint, but people need to stop casting down CT as though it was presented as the answer to their lack-of-content complaints. If anything, it should help even more people to get to that point, which might make the demand for fresh content louder. X)
