Guild Wars 2

So if I unlock pvp t3 human armor in pvp and after April update I can use it in pve? Like I spend 10 gold unlocking it in pvp and I can use the skin in pve instead of buying the whole set in pve which is 100gold?:0

Well T3 Cultural Armor in PvP is around 60g and requires some glory.

With the April 15th patch, all gear earned in PvP and PvE will be usable and transferable between the two game modes. Depending on your PvP rank, you will gain transmutation charges, and that should be plenty enough for you to transmute your PvP skins to your current PvE gear (which, again, will be the skins you share between PvE and PvP).

So to answer your question, yes, but you’ll need to transmute them with the charges they will give you from your PvP ranks and the new reward chests from the PvP reward tracks.
