I told my players about minion rules and that I was modifying them to include 1 and two hit minions. I never tell them in combat which ones are minions in the first place.
I thought minions would be too easy as a DM. My players have a different opinion, however. They find them a dangerous addition to the mixture. Sure they go down easy, but they can still make the damage add up quickly.
If we wouldn't have given our Paladin the at*will ability to heal others with his healing surges (instead of once per day at*will), I would have had two TPK's in the first night. Our second session not so much, with only one player having a real chance of death. My players opinion is that 4e is much deadlier than 3.x. I would have to agree.
