Well, from the example given it sounds like he did have his SC outfitted with MR items. Maybe he just got unlucky, but that's apparently not enough to render VotD useless.

Even if you can't kill the SCs with VotD, if you force your enemy to stop using them against you for fear of it, either to hide or to keep his kill count low, then VotD is effective.

And I have no idea what you mean by VotD honeypot. Please explain?

So most of your long list of conditions is irrelevant. Either you stop using SCs or they die. High MR is the only real counter if you want to keep using the SC. So balance depends on how effective MR is against it.
