One thing I have done with my 4e group is to only use the even levels. For the last level-up they went from 8th to 10th and will go to 12th next. Basically it turns 4e into a 15 level game.
One thing I have wanted to try out is to only allow a short rest once per day and require a week's rest rest for an extended rest.
The problem with spreading an encounter budget across multiple fights without short rest is that you roll initiative each time (presumably) which makes initiative far more important and means that initiative optimization can result in no combats being threatening, at all.
It's very easy for a group to kill several minions or a standard (or even an elite) before it gets to act; usually you make up for that by there being a bunch of other guys as well.
This can be particularly painful if you have a mix of initiatives, with a couple slower types and a few faster types, where the slower folks never act at all.
I'm very wary of this in fact - my plan is that initiative starts when both sides are aware of each other (after any surprise, in the usual way) and ends/resets only when the party are aware of no monsters (including if they choose to withdraw beyond perception range) and choose to "stand down".The problem with spreading an encounter budget across multiple fights without short rest is that you roll initiative each time (presumably) which makes initiative far more important and means that initiative optimization can result in no combats being threatening, at all.
Yeah, I normally only print a sheet every other level. I've found it works best to print only the odd levels, though. All it takes is a few notes to indicate things that change every level, e.g. hit point totals.Having to reprint character sheets 29 times seemed excessive.
