Games like this tend to have a short lifespan I have noticed, probably as each new title is released everyone moves onto that - and with a new/less known IP you get less people hanging on as the next best thing comes out.
I logged into Section8 last night and had a few games, came second (3 on each side, rest bots) with 400 ping, so not bad I reckon. A lot depends on fitting out the right loadout/kit to suit your playstyle then making sure you play to those strengths. I still enjoyed it, can't wait for the new one.
Trying out ArcheAge... liking it...
