[Suggestion] "Chaingun" alterations for each faction

I've asked my friend questions on what seems to be the biggest downs of each heavy weapon used by each faction (Jackhammer, Minichaingun, Lasher.) Both veterans and new players, Here are some minor alterations I've been thinking about after gathering some suggestions they've thrown out there;

In my opinion these weapons shouldnt have the aim down sights feature, instead have access to their own alternative fire, at the price of making the HA move at 66%-70% his/her default running speed.

MCG by what I've been hearing would do very well with a wind up alt fire, letting players ready it before entering a room, making loud and distinct noise as its barrels spin before firing.

Many players have mentioned its aoe attack causes heavy situational use, with a single press of its alt fire, the lasher raises its fins, bringing them down with each shot reverse as how it looks in its default firing mood as seen by Higby's demonstration. It could possibly fire a constant stream of energy similar to flamethrower for close range attacks or fire shots with no explosion effect.

For the Jackhammer, possible ammo increase to 12. This alt fire makes the JH make loud whining noises as another two shells are loaded into the barrel, with the electric coils in the barrel overcharged, all three shells are literally breaking while in the barrel making it fire a payload of pellets all at once, but at the price of a very large spread.
