I think another thing you guys forget is that war assets contribute to the war readiness level with estimated military strength. That doesn't necessarily mean that the war assets are utilized directly in the final assault on Earth. The allied forces didn't devote 100% of their forces to the assault on Earth, as we see from the extra scenes from the EC showing soldiers cheering on other planets. The war assets could plausibly be said to be put in use elsewhere in the galaxy to hold down additional Reaper forces while the battle takes place, stopping the battle from being a slaughter. I think it holds up.
