I considered banking the attack a while back, like, you skip it and the next time it pops up, it's stronger, but I really liked the loss of time by waiting and not positioning it well-enough on the grid to fit the timing of the enemies.
But another issue with it was that, in the later game, the enemies come so fast that you sort of have to use the weapon every time it pops up.
So that then counters the idea of skipping or powering up, especially when using it as fast as possible benefits you since every second you wait on using anything, causes a growing backup of timing.
