I haven't seen somebody go for a Dozer hunt vs Inf in a while, very audacious in this game.
I thought it was over since you weren't destroying his Barrack all that time, and he just kept on pumping out those TH's (he had like $10,000, he didn't have to stop). Had he upgraded mines on that Barrack, or just left a few TH's around it you'd probably be toasted.
