Would be nice to have a visual indicator when an AP bar is maxed at 30 (you currently have to click the action button to get a count). Since there is already an electric bolt that runs across the bar when there is enough ap to use the action, maybe a constant horizontal bolt across the entire bar when it is maxed at 30? Not major, but would be a nice addition.
why do you hoard AP? 
Sometimes the OBW/MStorm combo gets out of hand and I have more than I know what to do with
