Change my mind:
Stasis effect should depend on yours ship mass, or the ratio between your ship mass and target mass, Not only on the target mass
Currently the stasis weapons are basically useless, because their optimal range depends on target mass.
It's useless against very light S-cores (current meta), because optimal range is only ~25km and it's basically impossible for heavier ship to maintain such close distance
It's useless against a heavy ship, because it's max speed already very low, and you don't need stasis to catch it.
So I can't find any real purpose for using stasis weapons with this mechanics.
On the other hand, if stasis weapons worked based on your ship mass, that would allow for heavier ship to remove the ability of a smaller ship to run away.
But as stasis weapons have zero effect on max angular speed, this would still allow for a smaller ship to orbit a big one and try outperform big ship's tracking and turning capabilities.
