You kept lobbing forces of very inadequate value towards forces of rather higher value. Your biggest lob was at 12:05, lobbing 3.2k value at 3.7k, but more than half of that was your Grizzly, which doesn't quite benefit from being offensively lobbed into a mass of forces.

Lobster was not the problem here, and you'll want a Lobster regardless due to the threat of Placeholder.
