First, how accurate this is? I often hear different versions for how much crit you should aim for and I never figured this stat out. Some people say as high as possible, somewhere I read you need like 55% for ICC and even for less crit aim on some forums.Crit Cap
The crit cap is mostly based around the hit table, and the possible occurances on it, and mainly effects your white attacks (rage generating hits - melee damage)
24% = glance - reduced damage attack that only occurs on your white attacks, this is a fixed value and it cannot be changed with the addition of hitrating/expertise/crit etc. You will not get glancing blows on mobs that are lower level than yourself, it is tied into the weapon skill of your character in relation to the level of the mob/boss you are attacking.
Chance to miss - your hit rating effects this. You have a 27% base chance to miss on your white melee attacks vs lvl83 boss mob. Assuming you have the 8% hit rating soft (special attacks) cap, you have a 19% chance to miss on your white attacks, and therefor you cannot crit for that 19% of attacks either. By increasing your hit rating, you increase your crit cap.
Chance to be dodged - your expertise effects this. Base chance to be dodged is 6.5% vs lvl83 boss mob, and just like hit rating, that needs to removed or those attacks cannot crit. With 26 expertise / 213 expertise rating, you remove that 6.5% chance to dodge, thus increasing your crit cap. It is assumed that you will always attack from behind, so chance to be parried is not taken into consideration, but would also effect the crit cap.
So to assume the crit cap of a lvl80 warrior, vs a lvl83 boss mob, with 8% hit rating, 6.5% expertise your crit cap would be.
100% - 24 % Glancing blows
76% - 19% chance to miss
57% - Crit cap.
Crit immunity - lvl83 Bosses have a 4.8% crit immunity, regardless of your "tooltip crit", 4.8% of these crits would still be converted into hits. So your actual chance to crit at the crit cap in this case is...
Secondly, I was wondering as well what would be the best option for trinket and which stat to boost it with. Is it DBW(HC) + WFS(HC) the best choice? Or maybe DBW(HC) + STS(N) or WFS(HC)+STS(N) ? Need someone who understands this to enligthen me on this too.
I know many people here enjoy warriors and their marvelous stats calucations.
