I can assure you that games where each side of the conflict is actively trying only to destroy other side are not shallow and mechanically repetitive. For example, for a few years I played Warhammer Fantasy Battle at the tournament level - it is one of those games where each side tries only to wipe out as much of enemy units as it can - and mostly there were deep, dramatic, and skill demanding battles. The same case can be made for Descent - the fact that Overlord is trying to kill heroes absolutely doesn't have to mean that games will be shallow and boring - this assumption is ridiculous. Of course it needs the right game system - and in my opinion Descent's one is right for this, after some slight adjustments.
Also why do you assume that if Descent 2ed. introduced real conflict and direct confrontation it would mean that it will repeat faults of its predecessor?
Case in point - in Imperial Assault (which in opinion of many is improved Descent 2ed.) heroes death made a comeback.
I played Warhammer myself and while it's true that it truly requires skill strategy and tactics to play, your tactic usually revolves around killing the enemy units. The battlefield tells no stories and feels much more like some kind of arena than a part of a bigger world. It always felt very interchangable and unpersonal to me.
Descent 2 offers something else. You embark on a quest-filled-journey and visit some key scenes of the story-arc you are expiriencing. Your playingfield consists of highly individual maps, made up of tiles that represent characteristic rooms or areas of your quest, that play a themetically consistent role in your mission (looking for clues in the library or laboratory, raising zombies in the graveyard, being threatend by boulders in a small rocky passage and so on). Your tactics don't revolve around killing your enemies every time, although there are such quests. In contrast the thing you have to utilise your heroes and monsters for is highly variable and offers a very different metagame every round.
This is the reason I like this game so much: Your always have to adept your tactics to different challanges that make thematic sense within your map, quest and a bigger story-arc. That's excactly why I'm excited about this newest expansion, because it promises on expanding and deepening the integration of story and setting into the gameplay. If it fulfills it's promises I think it expands the base game enough to be called a genuine expansion and not just more of the same.
