You need WAY more homes. Homes will give you high BE when you draft deep (also better than running high forts and low homes/low draft for defense..) for war. High BE will help your TD's keep you at -95% losses.
Something like this...
7% farms
35% homes
13% forts
20% TD
10% guilds
10% towers
5% libs (increase this as your BPA goes up)
You need to stack runes before war, with this low % towers, but this way, you'll be able to sustain your thieves far better.
