My personal opinion on those:
Sidekick- Buff it by reducing the reticle bloom slightly to increase accuracy, maybe nerf it by requiring one more shot to kill.
Ravager- Buff it back to where it was in the alpha flights, requiring only 2 full bursts (6 shots) to kill instead of the current 3 bursts (9 shots). Also Buff the charging speed for the alternate fire by about 20%.
Hydra- Buff it to only require 2 direct fire and 3 homing shots to kill, as opposed to the current 3 direct fire and 4 homing shots to kill. Buff the reload speed by about 30%. Buff the homing magnetism by about 20%.
Plasma Pistol- Buff the Plasma projectile speed by about 20%. Buff the charged shot homing magnetism by 20%.
Disruptor- Buff fire rate by 15%. Buff magazine size from 10 to 12.
Commando- Buff it by reducing the reticle bloom increase speed slightly, to improve accuracy slightly in short bursts.
Bulldog- Buff it by increasing fire rate by 20%.
Heatwave- Buff it by tightening the horizontal mode spread slightly, and by increasing the damage of each bolt by maybe 10%.
And though you don’t have the Plasma Carbine and Assault Rifle listed, they definitely need a balance pass.
Plasma Carbine- needs 3 buffs, the first being an increase of the homing magnetism by about 20%, the 2nd being an increase in the homing lock-on range by about 5 meters, the 3rd being an increase in the plasma projectile speed by about 20%.
Assault Rifle- It apparently got a stealth nerf today which requires one more shot to kill, slightly increasing TTK, but it still needs more nerfs, specifically the reticle bloom needs to increase faster so that you need to pulse it more often at longer ranges.
