I'll have to review the VOD to be sure, but I think I only lost about 10% of my fleet over the entire course of the war. #HugeSuccess
The fact that I had such a strong techrate for so long made a massive difference.
I wasn't super far ahead in any one area, but I was slightly ahead in most of the fields. Slightly better weapons. Slightly better shields.
Also, I don't think I actually fought any cruisers -- mostly just destroyer/corvette swarms.
I mean, I only had 5 cruisers myself (and maybe 25 dest, 50 corvettes), but they are beefy and could tank damage.
And finally I always had a slightly bigger fleet. I think the battle with @AsaTJ was something like 6.2k vs 5.6k strength.
