Really like this Laser Cannon implementation.
If you're going to kill a Bile Titan or Charger, then you have to be able to commit to that target and let the damage ramp up, and there's just enough time to stop firing before the cell burns out.
Switch targets due to chaff or mid sized stuff pressuring you, or stop firing and you lose the opportunity for a large kill.
It's also nice to be able to take out Shrieker Nests and Spore Towers with one cell, unlike the stock Laser Canon that needs a few seconds cooldown before finally getting the kill.
