If you need a refresher on how hit rating works, go read my full-length mathy post about it from back in 2008. Its changing now, somewhat.
First of all, the Precision talent is changing. Currently it gives +1% hit chance per talent point, up to +5% total. After the patch, Precision gives +2% hit chance per talent point, up to three points or +6%. Also, due to the condensed talent system, not every rogue will have Precision fully talented.
Second, the conversion between melee hit rating and +hit % is changing.
Melee hit chance:
- Wrath: for level 80, 32.77 hit rating = +1% hit chance
- Cataclysm: for level 80: 30.76 hit rating = +1% hit chance (from Whitetooth at Elitist Jerks)
The spell hit conversion has not changed at all.
So, here is the end effect. Assuming that we’ll all have more than enough hit rating to beat the specials soft cap, then all that matters is the poisons soft cap and the white attack hard cap.
The poisons soft cap is as follows:
- if you have 3/3 in Precision, then its 289
- if you have 2/3 in Precision, then its 341
- if you have 1/3 in Precision then its 394
- if you have no points in Precision then its 446
Remember that you can go over the poison cap and it still is a benefit to your dps, but not as much as it was when you were below the poisons cap.
If you have managed to load up with tons of +hit gear and you are closing in on the white attack hard cap, then these are the values to watch for.
- if you have 3/3 in Precision, then its 646
- if you have 2/3 in Precision, then its 707
- if you have 1/3 in Precision then its 769
- if you have no points in Precision then its 830
Remember that hit rating has no value at all if you happen to get above the white attack hit cap, because you have already eliminated any chance to miss.
