I can't speculate on the resources. They would be depleted by at least half I would think depending on how many encounters ended in fights. I might actually run this at some point with my actual group just to see how things go. I can't do it with the current group because their magic items and the player rules are quite insane and would seriously skew the results. Our next campaign will be no feats or multiclassing. That would definitely be an interesting campaign to run this scenario against once they reach 13th level or so. That would be D&D by the base rules against the 6 to 8 encounter day. I think I'll go back and grab all the encounters. Then run it with the new group down the line. I'll be able to report the results against a near bog standard game, which would be more interesting to see.
If you push the 6-8/ 2 SR paradigm on them from early on (not all the time, aim for around 50 percent of the time with timed adventures - either hard time limits or soft ones - and 'you cant rest here, it's too dangerous' and 'not so random monsters') that'll make more of a difference than any banning of MCing or Feats. They'll be shocked at first, but once they get used to it, you'll find them conserving resources and avoiding novas and the game will balance a treat.
Also - design encounter specfically to defeat the players tactics from time to time. It mizes things up and forces the players to adapt.
