At the moment I've gone with 18/8/10/16/18/8 for my base attributes, Boreal Dwarf for my race. I'm only level 7, still in Defiance Bay, as I haven't had all that much time to play (I find I need a good couple of hours to really do anything in PoE). I took Biting Whip, Weapon Focus, Draining Whip in that order (felt I needed the accuracy early on). Powers wise I went
1: Mind Wave, Anitpathetic Field, Whispers of Treason.
2: Mental Binding, Pyschovampiric Shield, <wild card>.
3: Ectopyschic Echo, Pain Link, <wild card>.
4: Body Attunement, Silent Scream.
Wild cards just mean that I've experimented with a few powers in this slot.
After starting a little weak, this character quickly became pretty powerful. His single target CC is amazing, making fights against a small number of tough foes much easier. Also, with a small shield he rarely gets targetted in melee so long as I let him engage after the main tanks. Obviously no idea how he'll far against the toughest fights in the game yet, but it's pretty clear that he's viable. That said, I tend to think that a ranged Cipher would still be better in a lot of cases (can make stats more extreme, can more reliably do damage in tight confines, some spell targeting is easier as ranged etc.). I suspect once Mind Web appears though this changes since you then become as tanky as your main tank.
