Drow cleric - overpowered, you'll get no respect
Ogre ranger - If you go archery, I'll murder your first-born (see drow cleric)
Slith thief - I wouldn't do any rogues right now if I were you...
Avian ninja - (see Slith thief)
So, what does that leave you with.
Blademasters - New and hot hot hot!! Go for one of these.
Battlemages - The Old hotness, rock'em sock'em robots
Psionicst - Powerful. Why aren't there any at 50?
Crusader - Go for it, powerful, and almost non existant.
Fire warrior nexus - You will eat a vamp alive if you know what you're doing.
Non-rogue syndicate - Fun stuff right thurrr
Necro Savant - Fun, but don't expect to get anywhere in the cabal.
I could go on and on with awesome and totally easy to do combos...However, each time I do this...I roll 90351901095 million characters, rank them to 30, and start over...it tends to upset me. So much potential out there I don't know where to start...then I get something to 50 and just blow chunks or get impatient
