Emerikol
Legend
It has been expressly said that a slow-healing module will be in the DMG. So, unless Mearls actually told a bald-faced lie we know that part of Emerikol's want options will be addressed. As for alternate options for second wind and survivor, we can't know until we see the DMG or until someone in the know directly comments on it.
I am only acting on what Mike Mearls said. He said Second Wind would have no replacement. If he is lying or in error or unclear on that point and there is a replacement for Second Wind then I've said I would revise my stance.
I am not though going to buy a game no matter how easy it is for me to houserule it myself that does not offer any support for my playstyle. A lot of games are easy to houserule. I can start with a lot of different base systems and build my houserules on top of those. It would be nice though to know the guy(s) I'm giving the money to for their game don't oppose even the existance of my approach to gaming.
