It's easier than every to get a job to 50, and beyond, thanks to the experience bonuses. If you do other things while waiting for roulette the queues hardly mean anything. I doubt those zones you are talking about are COMPLETELY empty, too. Especially given that HW jobs start at 30 and thus put them in a prime position to spam FATEs in that level range. Costa Del Sol especially.

Are you perhaps playing during hours where less players are awake in general?
