"Old" Icecold had died off, we upgraded realms and revamped Reaper to 4.3.4 in an attempt to bring players back, which as you guessed did not go as we hoped it would. We have little staff at the moment, those that are able to do anything are......believe it or not...doing work on our development servers. The old website did not support newer patches like 4.3, and definitely would not support our custom legion project.
I would love to bring the old Reaper back. However, due to lack of player interest I don't think that's something we can do right now. Even if we did bring the old realm back, I don't think it would be able to pull the same amount of player numbers, again due to lack of player interest in the realm during it's final months. It has been thought about in the past, I decided not to go through with it as no one seemed interested.
If we have enough player support and interest in bringing old Reaper back, I would consider looking into it another time after our current project is released.
