Actually it all depands on who you ask...
If you are going to be grouped a lot, I suggest going Str, agi, and Wis.
If you are going to be soloing a lot, Agi, Str, and Sta.
If you are going to play mt for group Sta, Agi, and Str.
I'm grouped a lot and doing dps more then anything so my main stat is str, followed by Agi, then Wis. I raise Wis to get overall resist since its hard to find gear with good resists and stats if you aren't in raiding guild. I don't find int all that important since its basicly only for poison.
You just don't know when poison will get hit by nerf bat again...
