I am +1 your thread because I do agree with you... for the most part. There are somethings that I think you might be looking at incorrectly, though.
I remember the First Coil of Bahamut being lackluster in story content. You are pretty much playing detective to the aftermath of the fight we see at the start of ARR; nothing super interesting. It isn't until Turn 9 where shit really starts to get good. So, what I am saying is, "wait until the story is a bit fleshed out before jumping the gun."
Diadem is by far one of the worst things to happen in an MMO that is trying to solidify itself as a serious raiding game (or an MMO with a serious raiding scene). This content is a slap in the face to anyone who wants to take raiding seriously. Ya, and I never though about how the items in diadem will make crafted gear obsolete.
During 2.x the Coil weapons were always 5 ilvls higher then the current relic. Once they were about to release the new coils, they upted the weapons +5 ilvls. This is simply SE oversight not being handled properly. Actually, the entire ilvl gearing system for 3.0 and 3.1 is terrible, and can easily be fixed if they take 30-45 minutes to come up with a detailed gearing plan.
I think you are raiding for the wrong reason. This is simply a "Carrot and Stick" mentality when it comes to raiding, and I would be hard pressed to believe that you might not have any reason as to why you left your static due to drama. Although, as you mentioned, if you were one of the first groups to clear AS3 during its release, then you know that skill in raid is far greater than the acquisition of gear. And the fact that players will easily receive 210 gear, either from Diadumb or free Artifact gear upgrades should mean absolutely nothing to you. Someone who is full 210 ardent and artifact gear just means they grind low tier content. I don't mean to tell you how to think and such, but I know this kind of mentality when it comes to raiding is cancerous. You cleared the content, one of the best raiders out there, and you will be getting gear that other will not be able to get; is that not enough?
