I think I'm fairly close to having the Diabolos mission activated. The only problem I forsee is grabbing some 50-era equipment for my PLD, as I believe I sold most all of mine... Still, not outside the realm of possibility.
If you don't mind using me as the tank again, I'd be willing to move forward with CoP. It'll give me some experience for when I do the missions again with my mission static :)
If however, some other tank needs it a lot more than I do, I understand, as well.
*Also, if Diabolos is easier with a NIN tank (Never fought, don't know), and you were searching for a NIN tank, please disregard*
