I'm a 1.0 players and started with a level 50 BLM so I started off playing as SMN through the ARR story. I got a bit attached to it so I purchased the myth ring and bracelet so I can use between SMN and BLM. I started to only use BLM after that. I have a Stardust+1 and I'm full DL minus my Sorcerer's Coat, Vanya Hat of Casting HQ, Allagan Boots of Casting, myth ring, and myth bracelet.

Here is an image that tells you the difference between Allagan and Myth gear:

I plan to get the hat today since I'm holding off on the myth pants in favor of the Allagan on. I'm just curious to see what path people are taking to upgrading their BLM.
