Impressive how you have tried to defend this system and the falsified prestige they have while denying that you are not a collector, however there is a huge flaw in everything you have written to me.
For starters, that ‘‘Naxx40 is completely deleted and unrecoverable’’ is a lie, not only do they have all the npcs and the loot table in the retail database, they literally have an exclusive classic server, they could export it to retail or make a copy 1:1 from Naxx40, if they did not do it, it was not due to lack of time, but because they did not want to, now, I repeat that T3 is not an exclusive transmog, they eliminated it due to an error and this is a fact, T3 It is not unlike T1 or T2, which do not require any interaction with other players to be obtained, neither these nor any tier set from older expansions.
My problem is not mainly that you need someone to create it, since I myself guessed how this system worked before Wowhead or any other page published any theory, my problem is that there are so many blockers to be able to create it, 2.8m which then transform in 3.5m or more due to the material that you must create since not many are going to create it for you for less than 50k or 100k, and then you have to spend hours and hours farming in Scholomance to see if you drop any lamented pieces, this is not a good routine that requires effort or dedication, it is simply an excessively heavy routine that requires all your patience not to give up trying to obtain something that should never have been eliminated nor should it have acquired such high prestige
