And what if anything is different if you are using FireControl and you are firing them 2,3,5,6 by pressing button 2
With the exception of a bug with RACs and MGs for a short amount of time, Fire Control doesn't do anything more than a player can achieve in the game. It can produce artificial fire discipline and unique and steady fire rates, but in theory produced no "practical an unfair advantage" to a player using it over one who is not. (This is in disregard to what I may feel one way or another, it's how it's theoretically works.)
For example, a player with a great sense of timing and fire control will never attempt to shoot their UAC more than twice in a single cooldown cycle, avoiding unnecessary jam chances. However, any Fire Control type system can be set up to make it impossible to incur unnecessary jam chances by limiting the number of key presses to never exceed the total amount desired within the time frame. Basically, with Fire Control, a player with it properly set up may press the fire button on their UAC as many times as they want between cooldowns, but the Fire Control system will limit the button presses to register no more than twice in a set time (the projected cooldown cycle of the UAC).
Fire Control use to provide an advantage for RACs for a short while where RACs could deal more damage per second with "inhumanly possible" amount of clicks per second. However, this has sense been patched out of viability, and RACs can now no longer exceed the same amount of DPS as though one has held down the fire button on the RACs. (MGs also use to have this benefit, but has also been patched out.)
Only thing left that Fire Control can effectively do better (with in game benefits) from my experience is maintaining the ability to always have a Gauss charged nearly indefinitely, with short "recharge" cycle weaknesses, letting the player instantly shoot a Gauss without delay of charge (provided it isn't on it's recharge cycle) by constantly charging and recharging the Gauss as soon as it's charge time is exceeded. AKA: A player with a properly set up Fire Control for Gauss could, in theory, have their Gauss nearly always charged, and then upon the click of the fire button shoot a fast reactionary shot without need to wait for the Gauss to charge up before the shot.
Otherwise, as far as I understand your statement I'm responding to; You can, in theory, shoot your weapon groups in a timed manner within a set sequence (such as 2345), by strumming your fingers across the fire keys in a rhythm. On the flip side, Fire Control can do this within a single button press, making it easier and requiring less attention.
(This style of "fire control" is often used to quickly rapid fire weapons, of note AC2s, in a stream. It's actually more effective to shoot groups of AC2s in alphas for damage (pin point it all on a single location), but a stream of shells can deal more damage potentially because it's not all "hit or miss" and can be adjusted as needed to land hits on target. Also, ACs fired so quickly can produce blinding effects, possibly preventing accurate return fire. Can also be used for suppression roles. Mostly done though because "it sounds cool".)
