There hasn't been a heated discussion like this in a long time - so thanks for the entertaining early X-mas present!
Otherwise, I think this is a lot of sound and fury signifying nothing. As others have pointed out, it is supremely unlikely the developers will alter anything at this point, so this all comes down to house rules for MP games. So what's all the fuss about? You don't like the house rules, play another game.
IMO, these special scripts are highly unlikely to occur, but if they do, I can see how they can be unbalancing. Just had a normal MP turn where a Dryad with a Piercer (only 5 E gems - 3 w/ a Hammer - in CBM) gunned down an important enemy mage trying to assist PD. Her script was just 'Eagle Eyes', 'Fire Large Enemy', but she she still zeroed in on a human-sized mage (an Amazon, I think) at the expense of the PD units.
Game over in that fight, and that was just with whatever normal AI algorithms are usually run. But with special Bogus-scripts, and cheap ranged weapons, I can easily see how Bogus' tactics can be seen as game breaking.
But it would be so hard to pull of in MP (OK, Bogus has landed in my territory, and somehow I've got all sorts of free time to organize a Charm-crew, etc.), that it's hard to imagine it's worse than someone finding, say, the Circle Masters magic site, or a Conjuration bonus site.
In the end, I guess that's how I'd rank the outcome: Like finding Mt. Chaining, or that 50% off Conjuration site - yeah, potentially game breaking, but that's the way the lucky ball bounces in Dominions (but then I've seen that some people would like to ban powerful magic sites like that also).
