I just noticed (and I could be wrong) that I have 5/5 in Improved Blessing of Might which is supposed to increase your attack power giving by blessing of might by 20%. My rank 4 blessing of might according to the description is supposed to increase my attack power by 102. Thus adding the 20% it should be around 122, however my blessing of might only increases my attack power by 85 which tells me that it decreased it by 20%. Anyone else notice this or am I just off?
