Ok I may be way off on my math, but here's what I'm looking at.

Staff of Trickery
DPS = 186.5
AGI = 89 = ~1% crit (like 1.1, but who's counting) = 89 AP
AP Bonus = 180
STA = 133

Overall AP Bonus = 269 AP bonus

Titansteel Destroyer
DPS = 186.5
STR = 124 = 248 AP
STA = 105
Hit Rating = 54

Overall AP bonus = 248

So overall the staff wins on HP as well as AP bonus. The AP bonus is marginal at best. What I find interesting is that even though you lose 1% crit on the Titansteel destroyer you might see a good bump in the DPS just by adding 54 Hit Rating if you aren't near the cap. (Which seems to be sorely lacking on rogue gear oddly...)

I have noticed the lack of hit too...So much rogue gear has expertise and not hit! Why? Rogues always attack from the back, and have a crazy high hit cap.

Did they change some rogue mechanics?

No... their hit cap is still stupidly high... for pure white damage its still something insane like 700+. But their yellow damage cap is still only like 278 I think.
