Being 'good at refactoring' is only a desirable feature if you are spending a lot of your time refactoring code.
Why are you spending so much of your time refactoring code? Because your language isn't extensible!
Not a fan of TDD, eh?
Not a fan of silver bullets.
But your comment is still odd. Refactoring seems to be a core tenet of modern programming (regardless of TDD). In TDD in particular it's a central part of how you work, and so your remark sounds odd unless you also claim you don't believe in TDD :)
