Probably a *much* better idea would be to open a 2nd progressive server from scratch and let everyone start all over again (if they'd like). Give people something new to do while Veilous is still in the distance.

Then people could start at level 1 all over again, work toward getting their abu boxes, guises, mana stones, etc. Build up their new raid guilds, new chance to chase after dragons and planes and what not.
