Argonaut asked me this in a comment. I think it deserves its own topic:
Are there any statistics on how much defenses would be ideal per production of resources? (e.g. if one produces 50k of metal and crystal daily, then he needs an average of X amount of defenses)
Ideal Defenses per Production of Resources
Honestly, defenses are subject to many variables. You can’t say “1000 Small Lasers is best for a level 12 Metal Mine”. Why? It all depends on how tempting of a hit you are.
If you have a million metal, million crystal and 500,000 deuterium sitting on your planet, there isn’t much in the way of defense that will keep you safe.
Why? Because all defenses can be overcome with the right combination of Fleet and Interplanetary Missiles.
Just the other day I spent 9 IPMs attacking an inactive player. What it worth it? Yes! I have raided him twice a day for the last three days. I have collected well over:
- a million and a half metal
- a million crystal
- 300,000 deuterium.
For me, it was worth spending the 9 IPMs to wipe out his defenses… granted, the defenses were high, but the expenses were worth it.
On the other hand, I have seen planets with over 1k of small lasers, 30 plasma cannons and about 2k worth of missile launchers. Even though I could destroy that with my attacking fleet, it wasn’t worth it. The guy had less than 100k worth of combined resources.
If you don’t keep any resources on your planet, then you don’t need any defense. If you want to keep a lot of resources, then you need a lot of defenses.
So the question “how much defenses would be ideal per production of resources?” is only something you can answer. Do you want to fleet save regularly, or do you want to stockpile your resources and hope nobody with a bigger fleet than you can handle comes along?
There isn’t a formula I can give you to figure out how much defenses is needed per X level of mines. It all depends on how frequently you play, how often you fleet save (or use your resources), where your planet is located, and how active in raiding are your neighbors.
The more active your neighbors are, the higher the chance of you being scanned and attacked. If you are going to build defenses, follow the Building Defenses guidelines and keep adding more and more defenses until the raids stop. Or never leave anything around worth raiding…
