Defense is gimped. I hope this point does not need to be argued. Take a look at the stats of any weapon and its corresponding armor. Try out some ships in the fleet simulator. You will be inclined to agree. Yes, it does have its uses, but it is not doing its job at the moment. It needs improvement.
The solution also needs to be as easy as possible to implement. Although i would like to see huge, sweeping changes in ship combat, it probably is not going to happen in a patch. Not only will it take time, but it will also probably raise its own balancing issues and concerns. My point? Lets focus on what can be done.
My suggestion is pretty simple. Actually, its someone else's. I found it to be very effective: add a small HP bonus to armor. Lets take Ultimate Invlunerability for example.
Cost: 70 MP
Size: 3
Absorption: 9
HP Bonus: 3
For every installed module, it would add an extra +3 HP for the ship. Of course, this number can be anything balanced, but +3 sounds pretty good. Lower techs will have less of a bonus, perhaps counting in decimals like .5. Also, the cost of all armor should be cut in half. Defense now is just far too expensive, even with the HP bonus. I've mentioned this before but if you take a look at 1.0 numbers for armor, they were 4x cheaper while weapons remained completely unchanged. That means armor cost was quadrupled for absolutely no reason.
Although returning the numbers back to 1.0 would definitely help, i believe this solution would be much better. More HP means a ship can take a bad roll and keep on trucking, instead of being completely annihilated. Defense is far too random for its own good, but that was another post. I'll leave with some numbers in case anyone wants to play with the fleet simulator. I believe they are pretty accurate.
