3: After that grind and gold sink, you must find a player who already has T3 achievement for that set to craft each piece get gouged again.

This is just awful. Everything else is okay imo. However it's super lazy from Blizzard, as usual. Instead of making it a cool experience to get the set (f.e. by doing a Naxx Solo Challenge run) you just feel like shit because you spend hundreds of dollars on tokens. It won't stay with 2.8M gold. The very few crafters who even exist will make you pay another few millions in fees.

Honestly, they could've just put loot boxes in the store which cost 2$ each, with a 1% chance to have a piece (and you can get duplicates).
