I love how he thinks 12-13 lasers on each planet will stop a determined attack. The only time I've ever seen lasers used successfully in 3 instances:

1) (I think this was bit of a fluke actually) A guy in my bottom 10 random fam decides to about a 1/3 of his planets, and turn them all into laser traps. Stupid idea, but someone tried to rape him, and they lost a ton of fleet.

2) lasers traps. Get a planet very close to an enemy, station as much fleet as you can until lasers come in. Then build more lasers. When you have 1000% OB with only lasers, you're probably safe. Usually doesn't work if you get discovered.

3) During a prolonged war, have bankers build 0-5 lasers on planets closest to the enemy. Build 20-30 or more on all other planets. If it works, your enemy will only do ops on planets closest to them, so when they launch 50+ banker rape fleets, they lose it all. Odd theory, but I've seen it work. Sort of a spin on having bankers do a "laser jump" during wars, and hope the enemy uses old ops info.

Not that I'm being self absorbed and spammy, but it just seems like a bad cal with lasers was the root cause of these problems. That anjd lack of diplomacy.
