1. We have three kinds of shields, but we use one (grav mostly). So, keep just one, make it simple. Or...
1. a) Or keep all three, but add more fun by making them significantly sensitive/resistant to certain guns. If allied houses can't share shield tech, we'd need six kinds of them, one for each house plus civilian model. Further more, every house than should have one weapon tech more developed for tearing their enemy's shields down. (Lib guns would tear Rh shields better and vise verso)
(edited) It would lead to:
- police ships would need powerful police debilitators, as they never know who will they deal with. So they'd have less hull buster guns than navy. Anyway, it's not their job to go to war.
- navy ships would be more powerful to enemy's navy targets (all guns good for both shields and hull), but in trouble with tearing shields from others. But, war is their job anyway.
- local guerrilla factions would use both civil and local house tech, making tactical part and preparations more challenging
2. Maybe transport shields should be uber-resistant to capital ships fire somehow.
2. a) Maybe transport shields should be crazy strong in general, but positioned to cover just rear part of the ship. It would give them good chance to run from pirate capital ships. Their front and side part would be unprotected by that shield, therefore reachable to snubs. I hope it's possible to tweak shield's hitbox that way. I mean... for some reason it's hard to see traders now days.
