User Base Roles allow members of a legion to play a certain role on a legion base. When you choose a role you benefit the legion base and stay at that role until you leave the base or change roles. Here are a few examples:

Tactical Officer: Base Attack +0.5%
Helmsman: Base Defense +0.5%
Fixer: Hull +0.5%
Physicist: Shield +0.5%

And special user base roles that require Galaxy Points to use:

Miner: Mining +2%
Excavator: Artifact +2%
Scientist: Resarch +2%
Defense General: Base Defense +2%
Battle Captain: Base Attack +2%
Fleet Admiral: Base Attack +1%, Base Defense +1%
Builder: Base Upkeep -1%

Any thoughts?

+1 for the idea/concept

but I think lowering the % would be need to avoid abuse as OP
e.g.:
TO*60 = 30% base defense or Fixer*60= bonus 30% to hull --> way more than one seasonal base module can provide

maybe:
Tactical Officer: Base Attack +0.1%
Helmsman: Base Defense +0.1%
Fixer: Hull +0.1%
Physicist: Shield +0.1%

EDIT: still wondering whether this would not be a lot taking in consideration for race/profession bonuses for bases.

And special user base roles that require Galaxy Points to use:

Miner: Mining +2%
Excavator: Artifact +2%
Scientist: Resarch +2%
Defense General: Base Defense +2% (I would exclude as above is the Helmsman role)
Battle Captain: Base Attack +2% (same as TO role above)
Fleet Admiral: Base Attack +1%, Base Defense +1% (need tweaking - how many per one base?)
Builder: Base Upkeep -0.5%

Just add a limit, 30 max per proffesion. Also move the GP proffesions down though, perhaps to 1%

Do I really need to address this?

OK now were getting somewhere.

The numbers I proposed were rough numbers.

yes.

I think there are already enough things that require GP.
