Yeah - I agree. Someone has gone down and started making death saves in every battle our party has been in so far in our 4E game (tonights our 4th session). No actual deaths yet, but we always feel like we are in danger. I love that - makes for a much better game.
First serious 4E games last week (meaning we stopped play testing and we begin our campaign), the players were mostly rolling between 1 and 6 and the DM between 16 and 20... Result, after a skirmish against 6 gnolls (4 of them were minions), half the dailies were gone, as well as half of our healing surges... Yes, combat is as deadly as 3rd if you roll poorly!
