75k an T3-M4 (german PvE). What i also learned on the PTS: The new crafting material (exotic element) can't be earned by reverse engineering enhancements or modifications. I guess that makes mats-farming through pvp less profitable.
That is, unless, you have a synth/armor/cyber. PvP is still going to be the easiest way to get them... Plus Artifice & Cyber still gets the grade 9 mats from RE, whether PvP or PvE.
If you don't have a Cyber and a Slicer, now is the time.
