"Switch all power to front deflector screens..."
The Mobile Firing Arc mechanic seems like a perfect way to bring in directionally selectable shielding to ships in the game. Huge ships already have the Reinforce action, which is thematically similar, but it requires an action each time it is activated. Its advantage is that it functions to automatically cancel one hit against the Reinforced section for EVERY ATTACK during the round in which it is activated.
Of course, Small and Large base ships don't have sections. But with Mobile Firing Arc as a model, perhaps an upgrade could be brought in that selected a particular quadrant to be "Reinforced."
This would need some physical logistics to be worked out, because only a handful of ships have their base tokens marked out into quadrants. Some kind of clear overlay with additional quadrant/arc markings would have to be provided, probably.
What's the best game effect to implement here? A straight-up imitation of the Reinforce action, where every defense from the reinforced quadrant gets a bonus evade result? That would be a valuable (pricey) Modification card to a large ship. I'm thinking at least 5 or 6 points. Or maybe it just adds an evade die or two? This ought to be cheaper, say 3 points. Either way, the potency of this effect is considerable on a large-base 1- or 0-agility ship if implemented in Mobile Firing Arc style (rather than huge Reinforce style), where the selected arc retains its ability from one round to the next, until switched to a different arc via action.
Maybe it's too strong. Make it a one-use card? Thematically, it seems like the ability to reinforce a particular set of deflectors ought to be limited as energy is depleted. Or it takes time to recharge after deflecting a hit, so the function expires at the end of the combat round if any damage went through on the selected arc.
Or maybe the last thing the game needs is tankier large-base ships...
