I found a couple of entries in WoWWiki that explain and discuss hit rating in a consolidated, yet thorough manner. New goals. :-)

Melee:
http://www.wowwiki.com/Hit

Caster:
http://www.wowwiki.com/Spell_hit
note - even though the article still refers to spell hit (and the melee article to hit), it is updated for lvl 80 and the changes to hit rating.

The class/spec that I notice is missing is feral druid. I tried to do a couple of searches but didn't find a match. There are some general info posts, but they are flagged to be fact reviewed and updated with new info.

Thanks a lot for the links Eli! Good to know all those items dripping with hit rating will not be put to waste.

I did a little looking, and I would assume that feral druids would require the normal 295 hit rating to cap. If they have any hit increasing abilities that I missed, it would go down 33 points for every one percent to hit.

Thanks again for the links .

Good stuff Eli. So level 80 casters need 26.232 points of hit to increase spell hit 1%. A maximum of 446 to be 100% hit capped, which is a lot more than at level 70.
