I don't know how you guys managed to screw this up a few updates ago, but it has been established since Day 1 or so that SQUARE icons are things you drag to toolbars - ACTIVE abilities. OCTAGONAL icons are things that you DO NOT drag to toolbars - PASSIVE abilities.
But somewhere along the way, it seems someone decided they just didnt' give a hoot and started giving passive abilities SQUARE icons. Frankly, it was a stupid thing to do. It was a nice, simple system that you messed up. Please go through on one of the next updates and make sure all of the PASSIVE abilities have OCTAGONAL icons, and only the ACTIVE abilities have SQUARE icons.
