1) Has anyone tested whether Impact Bumpers lower the damage taken from Mines?
In theory it should.
2) And how does Impact damage from Mines factor in with the current physics?
I think with ships and walls, mountains, etc they deal a fixed amount of impact damage which is then modified by the ship's mass and speed.
Is the Impact damage from Mines the same? Or does it deal just a fixed amount of damage without any modifiers?
