Chaff in Elite is literally the only defense system that does not have any downsides to it. You can equip Dual Chaff launchers and spam it all day long. However the sensors on our ships are looking for thermal signatures and the only way to confuse thermal / infrared sensors looking for thermal signatures is to provide them with something hotter. Therefore Chaff is very hot. However deploying chaff does not cause any heat on our ships. This should be addressed, both for balance and immersion purposes.
The limitations of chaff are - 10 uses until you have to reload
Let us take a look at the other defense systems available in Elite
SCB - generate a metric ton of heat. Require heat sinks in order not to burn your ship.
Point Defense - Does not cover the entire ship, especially large ships. Has limits on its firing arc and rate of fire. Can be defeated by a large number of missiles fired at once.
ECM - must be manually fired and tends to aggro every ship it hits, assuming they were not hostile before
