My personal favourite builds would be charged strike zons and chargers. I don't really like to use builds that don't do much clicking. Always prefer builds that require clicking like charged strike and such
If you've never played an Assassin, try one. A kicker/trapper hybrid will get you through Hell just fine and she can do Baal/Meph runs no prob. C-Beat has a guide for this in the Assassin's forum. You just can't beat the plethora of skills this character has, a real jack of all trades, BoS, Fade, CoS, MB, Venom, the list goes on and on, and lvl 20 Shadow Master/Warrior can really dish it out (although not like the Valkyrie).
Energy Shield sorcs! Gogo base vit/no life hell characters!
Fading kicksin is fun too, as is frostmaiden...gotto love 1 shot minion group kills (if they're not CI). I just like the strategic firing as opposed to pumping out as many arrows as you can.
Melee Enchantress is ok this far, it should get more fun when she levels up a bit and doesn't suffer from blocklock as much anymore.
