Perhaps I should have said he wasn't interested in fighting BACK. I could barely do any damage to him, but when I actually tried to ignore him and play the game, he hit me. And it took a LOT of damage off me.
And by "boss fog", do you literally mean "fog door TO the boss", or the fog which stops you from leaving the area when you're invaded? Because I was under the impression that you couldn't leave the area once it locked you into being invaded (although, as I said, hardly a veteran of invasions, or the game for that matter.) If you meant actually going TO the boss, you're assuming that I was both near it, and ready to face it. And, frankly, nobody should feel pushed into facing the boss if they're not ready and willing, just to get rid of some jackass who's more interested in stopping them from playing the game than in playing it themselves.
Irrelevant now anyway, because I play it at home, where I have no desire or need to be connected unless it's to DL patches or DLC.
