Now there’s 2 ways we could follow up on this using t3 dessies and t3 cruisers as examples:
1.We go by interchangeable subsystems with separate subsystem skills.
2.We go with a ‘mode’ style like the dessies.
First because there’s not really that much variety to pack into several ships this all evolves around 1 hull constructed very similarly to current ships.
Some subsystem ideas:
Defensive sub:no.1 shield resistances increase,no.2 shield hp increase,no.3 shield booster amount increase(to keep it fair no1 and2 will have less midslots than no3)
Propulsion sub:no.1 warp speed and acceleration,no.2 reduced align time,no.3 increased afterburner velocity.
Harvesting sub:no.1 bonus toward ore harvesting,no.2 bonus toward ice harvesting,no.3 bonus toward gas harvesting
Engineering sub:no.1 increased powergrid,no.2 increased cpu,no.3 increased capacitor pool
Defensive:shield booster increase and shield resistance increase.
Harvesting:reduced cycle time
Propulsion:reduced align time,increased warp speed and acceleration.
Now for a gimmicky role bonus there’s a couple:compression just like the rorqual for this to be a thing you’d have to be limited on the amount of heavy water you can carry,gas compression would need to be added along with a new type of industry core.
Another bonus could be the ability to fit just 1 mining link,another would be reffiting in space without the need of a depot
Note that only one role bonus would go on the ship not all.
