Anything at all would be a huge waste of time. I did say :P
But the argument, I think, is still valid. Say Kevan Jones polled 45%. I think my first vote wouldn't be for either of the other two 'main parties' under AV, but _would_ be under FPTP, since it'd be the only way to get rid of him. Similarly, I suspect if the Lib Dems were significantly ahead, and there was a chance of unseating him, the Tories would probably vote tactically. FPTP makes it more likely, not less.
