Instead of counting the level of mods, it is much more reasonable to consider a more crucial part of the game, which is the tier of the mods.
Omega rocket one shots every low level players even though it is level 1. Same goes with Dart. The smurfs usually combine dart with low level ally shield and barrier. Low level players are demolished by these players. High level low tier mods simply can't compete with the high tier modules.
A quick cut for better matchmaking is simple: count the level of the BS level and the account level. 100-300 levels difference is unreasonable. At least make the margin smaller, like 20-50 levels difference to force the high level players use their best modules. Don't make BS fight a BS 2+ levels higher or lower. Even making 2 BS fight with 1 level difference sounds unfair. Make the margin thighter.
It is understandable that Hades Star doesn't have the most amount of players in the world, so BLS will take forever for matches against players. Nevertheless, ruining this game's matchmaking reputation will be worst than having a deserted BLS.
This also applies to WS fights. The absurd difference in power spoils most game. Make it so that a certain number of players with a certain set of BS and TS/Miner is locked for a WS scan. This way, matchmaking will be much easier.
If the game needs more player, get better advertisement system, and invent more fun.
BS is so standard, there is no variation. It is interesting to decide BS with variated module sets. Cerberus ships are also too monotone, make some variations. Add different enemies, even make the Cerberus fight a different vacation during an RS or WS if it is possible.
BLS is interesting, but it is only available in random. Make BLS for corporation fights. Make blitz fights, make duels, make objective oriented battles such as domination, death mach, or resource collection. The fact that BLS, BS, and all modules don't require any hydrogen fits this more engaging play style.
