Your capitalization, punctuation, and grammar are beyond awful, and your question is answered on the same page.
when my expertise is 176 i get 22 (reduces bosses dodge chance by 5,5)
at 177 i get 23 (reduces bosses dodge chance by 5,75)
so its kinda hard to get 5.6, or are there hidden "steps" between 5,5 and 5,75?
if so, the wow tooltip is kinda missguiding.. i will stick to 177=23 (5.75%) and not ~172~5.6% or whatever, tobe on the safe side.
i just hate when my specials is being dodged
