Reinforced Rockets' duration

The tooltip of this passive says that it increases your chance to be glanced […] for 10 seconds. However, the actual duration is equal to 5s. Granted, when the duration expires, 1 stack is removed instead of the entirety of the bonus, but i guess it still matters for this passive to follow the tooltip’s description. As for the 1 by 1 stacks falling off, that’s maybe intended already.
