I'm not sure if it's working as intended or not, but I notice if I exit after an instance run and I still have fortitude or another buff on, the stat increase carries over into my guild's roster. I'm not positive, but I think maybe paladin auras and such carry over as well.
I imagine there is a way to determine stat bonuses indirectly using the character's talent build and equipment, and their base stats based on class and race. That's all CTProfile uses and it's been 100% accurate for me.
I don't mean to disparage your work, or compare it unfavorably to someone else's. I love what you guys have done, and WoW Roster is an amazing tool for individuals and their guild. I just prefer the stats listed in the profiles to be unbuffed, and hence on the same playing field.
I'm using the most current update for 1.12.
Thanks for all the hard work!
