Equalizer for me is goal to have different strategies, with different ships sizes and ship roles. So Iยดm fine with extremely powerful rail gun on big ship, but hardly can accept it on 100K fighter.
IMHO is nonsense to make every weapons usable for every size of ships. So if you want to have small ship, than forget strong cheap rail gun for example.
Maybe, picture if the best example (I make it in hurry so apologize horrible quality) :

So, obviously, not everything is possible to match together ๐ Every technology has its size limit and cannot be put on everything.
