That would be helpful to an extent, and I know from past exchanges with you that you're much more focused on providing entertainment and seeing how people respond to your work than maybe some other devs so I know delays due to other mods not updating 'on time' are a bit tough to swallow. At the same time, I just finished crafting a stack of RP2 Managers last night. 28 stacks of redstone, 8 stacks of nikolite, several stacks of iron ingots and planks and goodies and such, and the worldgen allowances can't accountt for that. My blulectric satellite, with its 64 thermopiles, 10 kinetic generators w/ wind turbines and 80 or so blulectric battery boxes also would be beyond the bounds of worldgen protection.
So on one hand, I would love to see everything good to go so that your hard work can be revealed and showcased to the community, and on the other hand I've gone through 2 world resets just waiting for the FTB pack I had in mind from the beginning and having hours upon hours of progression reset for an update isn't even really an option for me. Even if updated versions of the packs came out tomorrow without RP2, I wouldn't update. With respect to your hard work and talent, there's nothing in that update that's worth what it would cost in resources and time to rebuild what I'd lose by upgrading to a pack without RP2.
