Hi (waves).

I've been playing around a week (instantly addicted) and have made great progress through the quests and zones, but my level doesn't seem to have kept up.
I'm stuck now, having completed all of the chain-quests up to 'Miner McPain-in-the-rear' but I'm only level 17 so can't seem to get any Numa Prime quests yet...

How can I catch up 3 levels without having quests to do?
Should I just grind Delta 7 over and over?

Thanks in advance,
Medique
