I generally find "big" TBS strategy battles to be the most interesting one, though of course it should be a little sped up from D:OS1 then.
Then again most TBS games don't offer the terrain altering properties D:OS1 showed.
It would also solve somewhat the 4 players - 15 opponent effect D:OS sometimes had that you have more to do yourself during each battle, even if the power level of the includants is slightly lowered to compensate. Allows you more different specialisations, and thus also more proper direct countering in combat as option.
But I guess that's just my dream
