Hi Divinepower.
For me at 28-29 i beelined straight for zek. Those orc grunts drop chests it seems about 1 in 4. Armor drops sell for 50 - 90 sp on average. Not bad exp too

)
Right now I'm doing D'Morte Burial Chambers, easy for me as a bruiser at 28, and i'm now addicted to the place at 31,

). Only thing is, there are many 'grouped' monsters (v or vv cons) so work that pet for aggro control. Again, good chest drops, in fact i'm farming trying to find a set of D'Mort Light Armor, (I've found the arms, and it looks fantastic, with good agi stats for me).
I know these spots arent green, but green mobs at 29 dont really drop good loot (3-10 sp range).
