I don't know. You've proven, I think, from a competitive standpoint, 95% (or more) of the stuff in Dominions is useless. It really doesn't matter what nation you take as long as the mages are good enough to get you to the few summons and spells that matter. Don't get me wrong. A lot of people like this. Your strategy is just the purest form of the mage/summons/castling winning strategy that I've seen so far. I could also be missing something and talking out my a**
It's also possible that I'm just a sore loser and want the game to function as I want it to

It's just that there is so much variety present in Dom2, I think it's a shame all most all of it seems to be just fluff. I doubt the designers intended for it to be this way.
Maybe all of Zen's mods need to be used together if the intention is to inject a little variety into the game. On that note, maybe you should post your Dracolich strategy in the Zen mod thread. I think they are looking for feedback. As you mention, it seems that the Dracolich is either underpriced or should have his immortality removed (not a good idea, in my opinion) or his protection and/or defense reduced or something. But, maybe not.
But, I'm stubborn. So I'll play again, try to counter your troopless strategy (without resorting to the same strategy myself - no point in that, it's been done), and probably end up in the same situation
It is fun, though, trying to think of counters. It's called "Yet another game", you say? I'll have to check it out to see if there are any crazy rules or if the map is too big. I played one game on Faerun (sp?) and never again, man.
