A consistant stream of shield regeneration is great, but no ship should be \"invulnerable\" to other ships that are unable to outdamage a larger ships\' shields.
I don\'t mean to sound like a heritic or anything, but I think shields should be somewhat like the HP systems of games like Battlefield and CoD. Here is my idea:
When a ship is being attacked, shield regen should instantly shut down. Shielding can go either way at this point; Either the ships\' shield load (See this. Xiphon makes a good point about why 2 types of shields blocks are important.) can continue towards zero, or the ship manages to avoid damage for a certain amount of time in which case, the shield regeneration will turn back on regenerating shield load back to full. This actually makes all ships no matter how large, vulnerable to a much wider spectrum of other types of ships.
This is where my other idea of adding Shield capacitator blocks comes in. with two seperate blocks (Sheild Regen and Shield Capacity), people will be able to make their own variation of defenses according to their preferances.They can take low shield regen but high shield load, or they can take high shield regen but low shield load, or they can take a versitalle amount of both.
The only problem with having a shield system like this, is that I can\'t really figure out the math to balance Sheild Load and Regen... :P
