PvP Tickets
Your league progress – the method by which you acquire tickets – will reset next season. The ascended legendary backpack is fundamentally designed not to be acquired in one season. That is, if you have no tickets from seasons 1-4, you couldn’t have acquired it yet anyway. (EDIT: You CAN get the ascended one in one season, but ascended is just a step to the legendary, which follows what I just said.)
There’s always this subtle chance that Anet will follow through with the idea of making it more expensive/harder to get next season, but I’m hoping they have the integrity to give us a full season of warning, or at least wait for 2018 to roll that out.
So yeah, just get to the end of Byzantine, and next season you’ll have the backpeice within a couple games. Not ideal, but not a complete waste of time.
