I ended up buying 2 or 3 pieces of gear with currency I farmed doing the low level roulette for a bit, along with breast tribe dailies.

I found main scenario roulette both takes too long (for my liking) and the queue is generally long as well. Just 2 more dungeons and I'll get access to the high level roulette.

(I've noticed that the roulette is MUCH quicker than choosing to queue for a dungeon directly, so I've been hoping the 2 I need for GC rank up and the level 50 story crop up as one of my random low levels soon)
