So I purchased Arktech Revolution but its still showing my faction for Chimera as..

[Valethar]

"Chimera Arkhunter".
Basically: A darker version of Nolan's outfit.

I don't even know how I missed that until now.. LOL

heh. I hear you. I just checked one of my toons and realised she had six 7th Legion outfits.

not available because I need to purchase the DLC. I have logged and shut down, logged back on. Tried this 3 times, still showing I need the DLC. Trion, can you help with this? Or anyone for that matter.

If you have Arktech Revolution then you can earn chimera rep anytime that you have a level 5k drag you into an expert Co-op, or get to 5k so you can ready up for experts yourself.

However if you get the message that you don't own the DLC, then you either:

1: Downloaded Arkbreaker and not Arktech
2: (if on console) Bought the Pc version online instead of buying it through your console's marketplace
3: (if on console) haven't linked your console
4: screwed something up or have a bug and need to contact customer support.
