Germany's dominance mostly just hurts countries that have to depend on the Euro, so not the UK. They experienced a little bit of the Eurozone's double dip recession brought on by premature tightening in 2011 but that was mostly a matter of trade exposure which isn't something that can change just by leaving the EU. And since the whole reason for the UK's trouble then was getting less trade from Europe then abandoning that trade altogether would be strictly worse.
