Thunderlord: Stat wise it follows traditional more impact less fire rate build for machine guns. However, with it's perks it eliminates the concept of this gun firing "slow". The first effect upgrade is feeding frenzy where kills grant faster reload speed. Almost immediately this is a good start for Machine Gun because of their notoriously slow reload. It's second effect upgrade is Lightning Rounds. This is the center piece of the gun because not only does it fire faster when you hold constant fire, it also becomes more accurate. Finally the middle three upgrades effectively benefit this gun. If you're using Perfect Balance, stability is increased so much that accuracy is achieved quickly when coupled with Lightning Rounds. Field Scout gives more ammo, more ammo = more shots fired = more effective Lightning Rounds. Flared Magwell destroys the whole idea of waiting for your Thunderlord to reload, faster reload prepares ammo faster which can be used earlier achieving Lightning Rounds immediately. Super Good Advice: Low impact but high fire rate. This also means relatively low range and low stability. First effect is Crowd Control, which is arguably the best upgrade for machine guns. It allows you to gain more damage every time you kill with this weapon. Second effect is Super Good Advice, which can bring missed ammo right back to the magazine. Note it will bring [b]some[/b] back, not all of them. Overall the real reason why this gun doesn't perform as well as it should is that the middle column effects don't compliment it's abilities as well as Thunderlord does. The first of these effects is Single Point Sling. This makes aiming faster, especially when using heavy weapons. However, the differences between having it and not having it is pretty insignificant because aiming is already pretty fast in itself. The next effect is Hand Loaded, increase range. While this negates some of it's accuracy issues. It's not enough to overcome them because of it's terrible stability. Finally, like Thunderlord, it gets Flared Magwell. However, unlike Thunderlord, Super Good Advice has notoriously slow reload. To put it into perspective, when both weapons reload without Flared Magwell, Thunderlord reloads twice as fast as SGA.
