They will reset everything gameplay related, including enderchests, so putting items in your enderchest is pointless.
If Protection 6 is added again More people will quit. Protection 6 was the worst Idea I think they put on Factions.
Prot 6 and sharp 6 was removed from the shop and wasn't buyable or enchantable, how would it come back again?
Protection 6 was removed due to its obvious non-compliance with Mojang's EULA. I've already said this and am lead to believe it's true as Collin 'agreed' with me saying it.
Collin did say that changes would be made to the content of rank packages, but as of yet nothing has changed ranks wise.
