The thread Rocdog posted is currently the best source of info.
The best t14 weapon is the Visionmaker weapon. It has both PvP and PvE stats. The t14 PvP from battlegrounds (Conjunct set IIRC) is good for PvP, but inferior to the Visionmaker set.
I haven't got a handle on how the NA set names (Conjunct, Discord, Abyss... ) relate to the known sets (New T13, T14 PvP, T14 PvE... ) so if anyone has a handy guide or chart that links the NA set names to their known tier status that would really help.
Cyasma set is non-enigmatic T13, Discord is Enigmatic T13, Abyss is Enigmatic Corpus HM T14, Victor's is non-enigmatic PvP T13, Conjunct is PvP T14, Deathstain is non-enigmatic T14... Regence and Visionmaker are obvious. :P
Thanks MonVert. Much appreciated. I'm apalling with names :)
I notice you need like 20K something Nexus point for the Materials, but anyone know if you need the Battleground Point too for it? Where do I get the Victor Trophy and the Spark?
yes you need to do BGs for the trophy, they are 3k each (credits)
