WotLK Hit rating as combat rogue wotlk - im going crazy

[S3mone]

Your text is understandable, but it has some grammatical and stylistic errors. Here is a corrected and more polished version:

Hi everyone,

I see everywhere that the poison hit cap is what you should aim for as a Combat Rogue in WotLK, which is 17%. Every guide states that, without buffs and with only Precision (5/5) providing 5% hit rating, you should aim for 315 hit rating to never miss poisons (and auto-attacks, of course).

However, 315 hit rating is not 12%—it's between 10% and 11%—and I can't figure out what I'm missing. Are there different values on Warmane, or is there another factor I'm overlooking?

Is 315 the correct number, or should I aim for more hit rating from gear to reach 12%?

Thank you for your time!
I hope you can help me. :)

You need to count in 3% debuff that's on target.

Also 1% spell hit is 26.23 hit rating so 315 hit rating is indeed 12% spell hit.
