As far as skills go, I use 5 aimed 3 packs 1 sp.

For gear, tarlok pot set with depraved blades. Go for a bonechill bow if you prefer bows.

With regard to strategy, focus on mana conservation against other rogues and timing to try to stun their packs.

Mages other than jebus in this bracket are a joke, just wait out shield then nuke.

Warriors it's just a slow grind down. If you have depraved, you can just go toe to toe with them and let your superior dps do it's thing.

In all cases, managing mana and pack usage is what separates the pros from the noobs.
