I made a Mythic back when they were hard (Terpsichore) then made another (Carnwenhan) during the Salvage v2 craze. Now I'm most of the way done making a third (Laev).

The process has gotten much easier, but in terms of my enjoyment of the experience: Terpsichore > Carnwenhan >> Laev. I can hardly even motivate myself to solo Einherjar these days to finish Laev. It was much more fun for me back when it was some epic undertaking and not something that can be accomplished with {Gil Toss} and 2 hours a night of events for two months.
