I feel like a lot of people are not understanding what's being said in the majority of this thread.

The op mentions that in the current format of gear progression, the raid patch comes out, all gear from previous patch is totally useless in about a day because higher Ilvl gear that is superior out classes it. This is true, which means after you beat the previous raid teirs content... there is no reason to go back in because guess what, you already beat the hardest content on the game so there's no reason to worry about your current gear anymore. The only reason would be for glamour and that really isn't an incentive for a lot of people.

In the coil series of raids, you actually have a reason you go back in and farm. You would beat the content, and then go back and do the content every week to prepare yourself for the next teir. Currently there is no incentive like that in Alexander at all.
