While I'm making these threads, let us have a small discussion regarding the ACU TMLs. So here's the deal: The Seraphim's version is extremely useful in ACU fights for a close-range snipe. While the UEF's version is very similar, it is different, and I believe Gorton when he says that the tiny difference makes it just about unwieldy enough that it can't be used for that purpose. Here is the comparison.
The upgrade costs are identical
The missile costs are identical
The missiles have the same Velocity (12), HP (3), and TurnRate (Varies relative to target distance)
Comparison from Seraphim's point of view
AOE (3 vs the UEF's 2, extremely important regarding close-range aim)
FiringTolerance (5 vs UEF's 2, not a clue if this changes anything, but it's worth mentioning)
MuzzleVelocity (5 vs UEF's 10. This makes a huge difference, and means the Seraphim can impact at much closer distances than the UEF's)
MuzzleChargeDelay (0.2 vs UEF's 0. This means there is a small additional delay between clicking and firing)
Clearly the Seraphim's is superior. The only real advantage is that the UEF's can be upgraded to Billy, but currently that's not much compensation. The upgrade and missile are both EXTREMELY expensive. The outer ring does a frankly pathetic 250 damage. Most significantly though, the Billy has a RackReloadTime of 30, meaning that instead of RateOfFire being limited by your economy (Like every other TML in the game) it is manually limited, and 30 seconds is a huge amount. It really does kill the weapon.
Three ways I see of looking at this...
1: It's fine, this is faction diversity at play, no need to change anything
2: Billy is tricky to balance, but there's no reason for the normal TML to be worse. Change UEF's to be totally identical to Seraphim's, or buff it slightly elsewhere
3: Leave the normal TML as-is, but give Billy a significant buff to make both the inferior TML and the huge cost worthwhile.
