Changing FC Alliance

Hey there- I've recently come into a rank 8 FC, with a nice house and nice things and nice chest things and all that. For various personal reasons, I might want to change it from Adders to Flames, but I was wondering, if I do that, does the company lose the unlocks it has in terms of housing, chest space, and avalialbe actions?

I've read that it causes the old reputation to decay over time once you leave that Grand Company. Do you keep you unlocks until it decays below the unlock level, or do you lose/keep them regardless of where the decay stands?

Thank y'all in advance.

Things like your FC chest, housing, and other items are not locked into what GC your FC is allied with.

I think the only thing it effects is the cost of FC actions.

Nothing changes from the change of th FCs GC allingment...
i'm not sure but only thing is the FC buff costs are tied to the allignment rank for the GC, so they will probably rise a little bit till you leveled the rank up again.
