It will increase the % on the buff, which again increases your overall attack value(which I chose). A good trick to battle stance is to keep it at 1 memorized runes, and rather just have a seperate set of gear with socket, put the battle stance runes into the sockets and put it on, then buff, take it off ,and wear your high attack value/skill set etc. Normally, if I buff with my normal killing gear, I end up at around 900 attack value, if I use my battle stance socketed gear I get 1500 AV for the same regen time as the 900 attack value(which is alot lower of course).
