please devs make x3 red haunts permenant because the builds on HF are expensive and I need a way to feel it not expensive so this is only the way I can build and upgrade builds in HF
Thy said that it might be a possibility, keeping it. They also said try might r working on doing the same thing with different epic battles. Read their post.
My guess is they'll keep it, but maybe require more seals per EB and/or make seals an EXTREMELY rare drop, meaning people have to buy nobs to run it B2B.
