I don't mind having to do Fieldcrafter again, honestly... Then again, Palrah (my badge-collector tank and blue-side Main), was the only member of my crew who ever had it, so it's not like I'd be doing it a dozen times. I wouldn't mind having to re-do any of the badges or Accolades, really.
That said, there is one thing that I absolutely must have on day one... And I do mean
MUST, here. This one detail will, in complete and total honesty, be the biggest thing that makes the difference between me being all gung-ho "Okay, let's do this thing!" and my having a much less enthusiastic "Eh. Maybe I'll rebuild Nemissary or something" reaction to a relaunch.
I have to have Kestrel & Company's angel wings back.
Those things were originally a twelve month vet reward, but they were essential to the vast majority of my favorite characters. I didn't call the crew "bird things" for nothing. If there isn't a way, at launch, for the new versions of those characters to have their wings, I just won't rebuild them at all. Having them look like they ought to means that much to me, even though NOT having them would sap a great deal of the potential enjoyment of having the game back right out. Sure, I had a few human toons I could rebuild. One of them (my crazy Death Mage dark defender-) was even a favorite... But without Kestrel, Palrah, Summer and Shade, it just wouldn't be the same.
So... yeah. I definitely vote for there to be some way to get our vet rewards back. I don't care so much about Pally's badges, or the Elysion base, or the crew's Incarnate powers or even Kestrel's absolutely obscene enhancements. I acquired all of that for them once, I can do it again. But there are some things about my characters that just made them "them" and any reincarnation has to have them. It may seem silly to get that hung up on a cosmetic detail... But being silly doesn't make my feeling about it any less strong. Asking me to rebuild Kes without her wings would be like asking me to rebuild her without Cardinal. I can't do it.
