you said you are only lvl 62, so unsure as to exactly how many AA points you have to spread around...
first off you said you were going Str / Wis, and liked having a bo staff. if you are going to go further into the Str line than just the +str stat bonus, you will have to give up weapons entirely for that to be beneficial, if you cant bear to go weponless, then dont do the Str line at all. i have at this point tried every AA line except Agi (no point)...i actually made a post with some parses a few weeks ago about the Str line where i said i did not think it was worth the AA points spent for the dps increase, but in recent times i have been called upon more and more to be DPS rather than a tank, and currently my setup is 448 str, 448 int, and right now i am going to try that in combination with 448 wis when i get a few more AA's, if that sucks then 448 sta ftw. I agree with everything said above ( Str line = more dps untill you can get 2x fabled t7 DW's or a fabled 2 hander with 108 ish DR) but in addition to that i would like to add something that might get overlooked alot, something i missed out on with my first go around with the STR line. Ranged DPS ... the Str line double attack will also apply to your ranged combat as long as you dont have any mellee wepons equipped, this in combination with the fact that T7 ammo is now available on vendors (eldar grove bow shop, or QH betweent the docks and CV) can make you a VERY formidable ranged fighter, IF you buy a t7 rare ranged wep (mostly only important if you raid) in a 24 man raid last night (not all 70's but several of them, and then a bunch of high 60's) with 448 str / int (100% haste, ~50% dps mod) ... i was one of the top the 3 dps every single fight, including the ranged fights, to drive that point home even further, there were several times when i turned off ranged attack for 5-10 sec until my name dropped a spot or two on my parse list...i did this because i actually did manage to pull aggro off the MA once with only ranged autoattack. now for the bad news...you might have heard ranger gripe about "paying for dps" in the past, well, one run thruogh lab and i used well over 1.5p in Adamantine Shurikens (~7g per stack of 99) because double attacking with ranged also means that you throw pieces of ammo at a time instead of one
