you can easily get full i235 gear from PvP in like 3 hours or less.

thats enough to do all the MSQs and even the final 24man raid.

Also, if you're a DPS you pretty much have instant queues into the 24man content for i260 gear, and 1-2 i270 accessories before SB.

So I suggest MNK for SAM gear, or Caster for RDM gear.
