Most active Data Center for pvp?

[Mistress_Irika]

What I am looking for is just frontline activity. I just want to rank up in the, whatever its called that gives you the crystals and frontlines work just fine for that. Thanks for the info guys.

I'm not exactly sure how true this holds now, but in terms of activity:

Aether > Crystal > Primal

Quality of frontline games are a different story.

Frontline is Frontline. I'd just go with whatever has fastest queues. That seems to be Crystal, tbh.
