Off the top of my head, buffs first followed by nerfs (Not commenting on the starting parts):
Buffs:
-Flamethrowers (GACHIRIN, NICHIRIN): Use WS type lock and a quick lock time on par to that of the WR73RS, keep their range at 96.
-ROC3: Increase damage to 550, not hangarable.
-DRAGON: Hangarable. Increase its shot velocity to match the SHADE.
-GHOST2: Hangarable and increase ammo to 120, or increase weight to 388 and increase ammo to 144 instead (but not hangarable).
-Change MIST2 model to MIST and MIST to MIST2, increase MIST2 ammo to 84. Both are hangarable.
-WR88H: Hangarable, increase velocity to that of the WR69R, increase stun to that of the HP (to match the Japanese description), increase damage to 232, and revert it back to fire in bursts of 4 shots.
-H2 pistol: Increase range to 400, increase heat to 2980 considering that this thing was deadly in Silent Line.
-GHOST: increase attack heat to 3725.
-ARGOS and ARGOS2 switch model. Increase ARGOS2 energy drain to 522 and ammo to 60. Increase ARGOS energy drain to 360, damage to 401. Both are hangarable.
-TAROS: Implement the "dual laser openings", if that is not possible, increase damage to 1672, discharge heat to 1962, attack heat to 6264, and usage drain to 8352 (doubled version of ELF2 at least). Increase weight to 536 and decrease energy drain to 229.
-LB3: Switch blade wave explosion with ELF3.
-TROLL: Fire splitting projectile like the other spread bazookas, better yet have it fire explosive buckshot
-CHIMERA: Lower weight to 1400, increase ammo to 80.
-CERBERUS: Increase damage to 2055, decrease weight to 969, increase range to 830.
-Bomb dispensers (I69BD and I80BD2) should "spray" their projectiles like the URCHIN, or have it completely overhauled to fire micro missiles like that shown in the AC3 intro. In the case of the micro missiles, decrease range to 290, increase energy drain (180 for I69BD and 340 for I80BD2), and have them fire a large spread of 8 missiles each.
-WB72M2 and NYMPHE2: Increase accuracy but decrease velocity.
-WB73MP: Increase range to 600.
-Torpedoes (82MGT and E96RMG): Increase tracking, maybe let it fly a little higher to prevent grounding itself.
-WB85MPX: Decrease weight to 1026, drain to 605, and reload time to 200 (Best used as a spam and drop weapon).
-Chain guns (WB69CG, WB72CGL, and WB03CGH): All renamed to be gatling guns. Remove magazine function to fire at full automatic like the FINGER.
-WBW78C: Increase attack power to 240, and remove magazine function.
-LG linear cannon: Increase range to 730 (or even 825) to function like a sniper cannon.
-LGL2 linear cannon: Decrease weight to 515, reload time to 56 (magazine reload time remain the same).
-H69S head: Decrease drain to 164.
-84O/UL need a slightly higher heat resistance or cooling to offset for its high OB heat (and weight).
-A71S2: Decrease energy drain to 933.
-GALAGO: Increase aim accuracy to 280 to reflect its Japanese description.
-A80S3, LANGUR, and most of the heavy arms don't stand out as much as they do in SL and require some overhauls to be useful. I don't know if tuning should be allowed on weapon arms, although that would open up a few possibilities.
-B69: Increase base boost power to 16905, tuned boost power to 17469 (Or 18605 if keeping default tuning amount).
-B72T: Increase base boost power to 19238, tuned boost power to 20007 (Or 20320 if keeping default tuning amounts).
-B90T2: Decrease charge drain from 5850 to 4388 (25% lower).
-Re-introduce a DRAKE-OX boosters: duplicate and recolour B81 to dark grey with white exhaust. Stats as below:
>CR-B09P
>Cost: 98540 Credits
>Weight: 190, tuned 180
>Energy Drain: 391
>Boost Power: 17752, tuned 18752
>Charge Drain: 3542
>Boost Acceleration: 3230, tuned 3553
>Booster Heat: 3765, tuned 3577
-Lower booster heat on all hover legs as well as tank legs (tanks to VULTURE heat level, hovers to VULTURE2 level). Hovertanks should actually "hover" as in of over water and such.
-LT69: Decrease weight to ~2400, as it seems like this part was intended to be a light tank of some sort with its low defence and cooling.
-FUGEN: Increase max lock range to 530, average lock range to 483.
-KOKUH: Increase parallel lock to 95.
Nerfs:
-ELF3: Use LB3 blade wave explosion, slightly decrease blade wave damage (80%).
-H3 pistol: Attack heat lowered to 2710. Increase damage to 235.
-LGL linear cannon: Ammo decreased to 53, and decrease attack power to 672.
-ROC4: Decrease damage to 464.
-YH70S2 head: Increase drain to 185.
That's it for now really, there are more buffs than nerfs because most parts just seem useless as in for now.
