Alright, as I am sure that some of you are aware, Spirecraft Shield bearers are not worth the extremely rare and finite materials that they consume.
For those of you who do not know what the ship does, It provides a large shield to your fleet (yay) while not being able to be repaired (ugh). Also, for some strange reason, they do not like to be selected with my military ships, even though their entire purpose is to protect military ships. For a ship that can only be manufactured in a very limited quantity, the lack of repairing it makes it almost unusable and practically a waste. I suggest Spirecraft Shield bearers are long overdue for an overhaul that could allow them to be repair while still not being unbalanced
Option 1: Spirecraft Defense booster
Instead of a shield that eventually wears away, how about damage resistance. Think about it, for small ships it gives a 25% damage resist, for larger ships (such as flagships) it gives a lesser resistance such as 10% at mark 1, with each mark adding 5%. This could allow you to repair the ship while not unbalancing it as the ships will still get destroyed, just not as fast.
Option 2: Spirecraft Accelerator
Essentially, this would let the ship act as a sort of tug boat, pulling slower ships along, not as fast as the quickest ships mind you, but faster than the molasses speed some ships currently travel at.
Option 3: Spirecraft Scrambler
This (possibly cloaked) ship would fly up to AI ships and reduce the damage that they can output, making it useful for mitigating damage that AI turrets do while the rest of the fleet goes out and hunts down the targets.
Let me know which option you would like to see as well as your own suggestions.
