I agree with you, but I don't think that it will be enough for those people who want this to be an RPG.
I think the best change in this regard is the obviously varying objectives for the OL (1st objectives were solely 1) harass heroes, 2) kill enough fast enough to deplete conquest to nothing)
With the removal of conquest there does not appear to be any more generic all scenario win condition for the OL. Win conditions are now dependent on the scenario, just as it always has been with the heroes.
So, I guess my biggest hope is for a wide variety of quests (possible quest expansions?) which would really challenge both the players and the OL to meet stated objectives above and beyond killing hero's and killing baddies. Although a good 'run in an kill da big boss' scenario is good now and then also. I wonder what the OL objective would be in a 'run in an kill da big boss' scenario?
