I like the new system. It makes things simpler and easier quite frankly. As Ric said, the "rush!" mentality is somewhat lessened.
There's still a lot of group-rushing going on through dungeons. Perhaps this system takes time for players to adapt with for the said mentality of rushing to be lessened? Perhaps the other system was fine and the arguments presented by those who rush dungeons weren't valid as they still keep doing it. (My observations in the console.)
I think there will always be rushing through dungeons, no matter the system you've got in place.
DM's a pretty good detriment to Dungeon Flushers. I do agree though the Dungeon Campers/Rushers are always going to do such regardless of rest system. This one does though, Slow them down Just a touch, Unless of course they are carrying a few hundred gallons of the new potions then it's just a brutal sprint to the finish.
For the generalist though, those of us that aren't camping, it adds a few more opportunities to the buffet so to speak. If Items like the tent and such are in play I was actually thinking if others would find it interesting that a Camp Option be added to the Rest Menu which would automatically set things like that up?
Anyway, still think it needs to be tweaked out a bit longer between stages since one of the things about it I really like, is in PvP situations you don't have a pile of people leaping across the safe transitions, resting, rebuffing, jumping back out, then repeating. That's a good thing.
