Guild Wars 2

I started playing after HoT release, so I don’t know if there is a precedent for this already, but will the stat selectable items currently in the game, such as LW3 ascended trinkets and wvw/pvp gear, be able to select the new stats coming with the PoF expansion after release? As far as I know there hasn’t been anything official said about this topic so it would be great to hear from a dev. What do you guys think?

I’m honestly doubting this.

Consider the Mawdrey backpack, which was released during LS2, and has selectable stats : they don’t include new HoT and further stats.
Orders ascended backpack from HoT, as well as the Luminate’s one don’t include new HoT and further stats either, which is a pity, given you require to finish HoT to get them.

My guess is LW3 trinkets will remain the same, but I may be wrong ; and I hope I am !

Likely not, judging from how it’s done before.

Legendaries however will have them added.

In the past HoT stats have been HoT-content only (and LS3 since it’s technically HoT too). I’d imagine they keep PoF stats exclusive to rewards from that expansion.
