Instead of the Support Marks we earned during the event the vendor asks for "Ebon Vanguard Proof of Allegiance". Kinda weird that we could turn in the crystal bloom support marks for defense seals but not the ebon vanguard ones.
Seems kinda pointless to add new weapons without any proper synergy with traits and such. If they dont make new e specs they would have to include the new weapons into the already existing specs.
