+Hit and +Spell Hit for PvP?

[Watto44]

Base chance to get a "white" resist* versus a level 70 mob/toon is 4%. There is always a 1% chance to get a white resist, so you want to grab 3% spell hit as quickly as you can. Note that spell penetraition has absolutely no effect on these "white" resists.

Base chance to miss an equal level mob/toon is 5% when you're not dual wielding. Unfortunately I have no idea if there is a cap on melee misses, but somewhere in the back of my head is the idea that there isn't. So I would be thinking of aiming for around 5% +hit.

On the same note, I'm not sure what the base miss chance is for special attacks while dual wielding. Is that still 5%?

* "White" resist is the common name. They are basically spell misses and affected by the +spell hit stat. They are called white resists because they used to be white in your combat log, where as resists that appeared yellow were due to the mob/player having resistance gear on. All resists are now the same colour in the combat log now.
