So, the title- my friends and I occasionally play and I'm rebalancing the game a bit for our tastes (I.e. Long Range Frigates actually being long range, for instance.) And the big one I"m running up against is one of the artifacts is pretty much considered a joke prize; the anti-bombardment one, as twenty percent MAY be a lot- but it just means the massive bombardment fleet just hovers over the planet a bit longer.
How easy would it be to rearrange that to add, say, +10% or +15% shields to a player's ships?
