22 Assassin
24 PoM
22 Tos
24 Tos
20 Guardian
2 14 Necro's

In regards to stealth, there is a button at the bottom of the minimap shaped like a diamond(?) the lighter it is the easier mobs will see you, the assassin is pretty cool but sucks during the daytime because their stealth is easier to detect, other than that they do decent dmg and if you attack from stealth the mob is usually dead in 2 hits. I'm currently sick of the <20 zones , starting to work on a PoM main with a Tos backup, works really well, good aoe dmg, was playing last night and just destroying mobs non stop just using the weakest HoT and just melee'ing them (even lvl mobs) I found the Necro's extremely weak , and rangers at low levels are a pain. I was thinking of trying a Conqueror with a Bear Shaman as i have 2 at around lvl 8 that i could get to 20 in no time.

Pom with their knock back/AOE Damagae and then the Lightning strike from the ToS mows down mobs quickly though.
