I did a couple 4-5 minute parses and according to my character screen I have 8.15% crit from rating and 8.37% crit from intellect. This should be 16.52% crit but doing these combat parses on the dummy im getting 9.5-10.5% crit chance on all of my spells (save for SW which only had 10 casts so not applicable, and MF which had about 15% average crit due to my 2 piece t10 bonus).
Am I stupid and missing something obvious or is this an issue others have noticed as well?
