Do you need UW's or just last teir epic augs?
Again, you dont NEED UW....even if you're just running 6. But it helps a metric shit ton if you do, and if its current. But that involves more tedium than you can imagine.
Are the server admins tuning content with characters in max gear and expecting every single player to be in said max gear to overcome it or are they using chars in lesser gear to tune the content they create?
To go to the next tier you must have the maxed epic and armor from the previous tier....so yeah, they are.
When I say "max gear" I mean full UW's, full UC's, BiS jewelry items, max augs, along with proper armor. Are all those required or are they just slapping on the full epics, armor, a few "good" pieces of jewelry and some mid-tier augs? Are they tuning with 6 boxes or 12 or 18? Are they tuning drops for a typical player of THIS server using 6, 12, or 18 chars? And is that tuning resulting in the player retention they are seeking? If not, what areas are they willing to compromise in order to increase player retention?
And all this is just really the basics of content tuning without getting into the "hard core vs casual" tuning that most live MMO's are forced to deal with. What we are talking about here is just your "core player" tuning.
And you are correct, very few MMO's give you options when it comes to progression options. Most MMO's have very strict raid number and group composition requirements that are sometimes rigidly enforced. This server obviously does not adhere to that, but then those options also make it more difficult to challenge the various different play styles on this server. As I said, the person who brings 18 to an encounter designed for 12 can't complain that it's too easy. Likewise, the person who brings 6 shouldn't be complaining that it's too hard either.
Edit Typo: Should be BiS instead of BiC.
