Soban is pretty weird balance wise, they have some very strong options and some terrible options.
as it stands the Armed Logistics Modules(ALM) are the only thing keeping Soban Competitive with its very weak carrier, while their high DPS railguns allow them to snipe carriers more effectively than most other factons.
So I have a small list of my own recommendations to better balance the faction and hopefully open more effective builds.
Substantial increase to Soban carrier PD damage (should still have the lowest DPS but should still be comparable to other carriers)
ALM deployment range nerf, should be comparable/slightly better than Khaan missile ranges, consider ALM max deployed cap
Soban BR, Disruptor beacon deploy cost removed, Beacon has 8 second lifespan, cannot be targeted/destroyed
Soban BC, improve accuracy and increased movement speed (reliable damage output and better mobility to off sets its inferior DPS to Coal variant)
By increasing the Soban carrier PD effectiveness it allows the Soban carrier to play a far more proactive role in the match than simply deploying ALMs and opens up less railgun centric build orders.
Nerfing the ALM deploy range restricts the versitility they currently possess, I have been able to deploy my entire force to attack one flank while deploying ALMs half way accross the map to stop a enemy railgun push, purely with ALMs.
This gives Soban so much more flexibility in the late game along with the excellent scouting ALMs provide, restrict this would be a step in the right direction to better balancing the Soban faction.
The Soban BR can be a real CU sink, deploying probes and disruptors, I feel taking the cost of the disruptor and making it a timed ability would encourage more pro-active use of the BR as well as make it a far more effective tool.
The Soban BC currently is a over priced, up armoured Railgun with limited mobility.
Opting to use Soban BCs forces you on the defensive, you need high ground bonus and you cannot react to enemy attacks.
Improving their accuracy would allow them to more effectively operate with out the high ground bonus and it would make their lower DPS more reliable.
Increasing their movement speed would then help them actually get into combat(we are only talking 5-10 more speed, putting them on par with Gaal/khaan cruisers)
This would open up a much more varied late game for Soban while also reigning in ALMs offering opponents more ways to punish Soban.
