breach rifle
1.bring back old damage
2.increase the recoil
3.tighter bullet spread while aiming
4.bullet spread will need to expand while hipfiring to counter act "spray and pray"

hmg
1. increase how fast its effective rating drops the further away the target is.

swarms
1. make them faster to catch up with dropships

dropships
1. give counter measures against the swarms i.e. make swarms destructible by turrets for ex a merc in a dropship is manning the blaster turret while this gun is ineffective against infantry it will be useful in blowing up the swarms chasing the ship. since turrets cannot aim directly behind or in front of the ship this requires the pilot to outmaneuvre the swarms in a way that allows his gunner to be able to lead the missiles to destroy them. plus since the dropship has two turret slots it will still be able to fire upon enemy infantry with the other turret slot if that slot is not being used as a counter measure itself.

this will also give a new play style to dropships as they could then be extremley durable mobile spawns as they could have two blaster or railgun turrets dedicated to eliminating swarms so that the ship can deploy more soldiers.

IMO:

Lazer rifle just needs a slightly faster overheat. Anything more, would be overkill.

MD needs to go back down to having 2 less rounds. (original drum capacity) Anything more would be overkill.

ARs are fine, except damage on militia/std should be back down to 30, Duvolle should be bumped up to 34.5. Only other level of differentiation should be a 5% increase in ROF as you go up a level. That way, the damage per round only goes up by a couple points, but the DPS goes up more, because of faster ROF. This along with the fact that accuracy goes up with higher level ARs, would be enough.

* Regarding Breach, they just need to be bumped back up to original damage. (and give Creodron it's old 42 round magazine)

HMG just needs it accuracy to drop at the farther ranges.
