Can't figure this out. I am hit capped (3/3 in precision and 167 hit rating) and expertise capped (32 expertise 265 expertise rating) and my autos have misses (the white damage text NOT the yellow). I do not believe it to be a visual bug as enemies don't take the damage from the miss. It's extremely frustrating. I found some old thread talking about some silly hit rating cap of like 26% that no one gears to but that seems to apply to spell cap (or special ability in case of warrior) than auto attacks.
You want 8% for your skills not to miss and 26 expertise to bypass dodges.
Dual-wield hit cap is absurd 27% against bosses.
Warriors have this thing that their off-hand AA won't miss if Heroic Strike/Cleave is queued.
