I'm indifferent to reraise being implemented, but I think we should just see how the dungeons play out before arguing over this. For all we know there could be checkpoints to come back to if the whole party wipes instead of starting all the way over, but still at points where it's a bit of a setback but doesn't have people going "OMFG we gotta start all the way over????" Although, with SE, starting all the way over in a complete wipe wouldn't be a surprise ...
