Well then...

I had over 50 exotic engrams saved, decrypted one, then infused it and repeated that until I was around 324/5. Did the court of Oryx for a decent artifact and cashed in all my HoJ tokens/cores for HoJ packages (they contain class items). Did some more decrypting and infusing then went into PoE. I've only done this on one character, but I'll be able to send items across for the others to infuse. Easy money.
