I searched forum but didn't find something about it so I just write it here (I think it's a bug but I don't have 30 posts anyway!)
It's about the elemental shaman talent "Elemental Precision", which gives 100% of your spirit at addition spell hit rating.
Without this talent I have 205 spell hit rating from items which is correct. With this talent I only have 348 spell hit rating but I have 301 spirit. So if I understand it correct, actually I should have 205 + 301 = 506 spell hit rating instead of 348.
Hope some other shamans could check it, maybe I'm just wrong and if I'm correct and/or it's a bug, I hope someone with more then 30 posts can write it into the BugTracker.
