Waah.. nothing should become unavailable it should remain always obtainable even the Legacy items it was a 3 months of sub campaign to obtain so just chuck them on mog story for like $20 since wont include a discounted sub. No In-game items should be permanently unobtainable even the trophies/titles should get re-used.

You got your exclusive time with the toy now it's time let others play with it.
