Ranger + Rogue duo. good levelling spots?

[Anxarcule]

Currently at level 18, we tried UGuk spiders and it was decent enough exp, but zone itself was too crowded. I think if we were cater to the strengths of the classes the best thing would be for Ranger to snare and keep aggro + bow kiting while Rogue backstabs to death, so am thinking katanas might be good. With this strategy considering we shouldn't be getting hit too much, I think high yellows would be a good target - hopefully the ease of this method will alleviate the ZEM received from indoor dungeons.

Crocs in Oasis could work I suppose, but I've spent so much time there back on live and a bit on wiz that I'd prefer a different zone Ideally we'd want somewhere to spent the next 4-5 levels without moving around
