what is the fastest way to farm GP out there?

this sounds like another relic grind, I hope they lower prices to something reasonable.

I don't really see MGP prices ever dropping. As Vidu said they already made it easier to reach your goals, you just have to put in the effort. I have only done the occasional fate (Cliff hanger as I hate the other 2) and Anyway the wind blows and Time of your life. Mix that with the 3 daily tickets and I have gotten about 500k that I am sitting at now and that is with me having spent 200k when AST came out to get the full Gambler set.

Triple Triad against Indolent Imperial used to be the best before 3.0, something like 5000+ MGP per hour. There's probably better opponents out there now but haven't explored.
