Long time annonymous reader, first time poster.
My guild just downed Gruul for the first time tonight and Recap gave me some interested results in regard to my hit/miss ratios.
I have 350 weap skill (I know, missed it last respec, my bad), 196 hit rating (damn wastewalker 2-pc eludes me

) and Precision.
196 hit rating / 15.77 = 12.43% + 5 (precision) = 17.43% hit boost.
Going by previous posts in this thread, 25.5% base miss chance against a lvl 73 (boss) mob, such as gruul, should give me 8.07% miss chance on white dmg. Recap (cleared right before the fight, so this is JUST Gruul dmg) put me at 11.2% miss (actual misses, after factoring out dodge/parry/block, it was like 19% white swings failed to land). What am I missing? I had close to 1400 white swings, I'm assuming statistical error won't account for a nearly 40% difference between the 8% theoretical and 11% actual miss rate over 1400 swings. Whats going on here?
Also, side note, what are other Combat Dagger rogues getting in terms of Backstab hits on Gruul? I was noticing upper 1900's and lower 2k's.
