I'm not sure how you're reading that I'm asking for so many things. I'm asking for a short stun to most new AOE patterns as a clear punishment to the player who makes the mistake, instead of pushing mechanics that punish the party as a whole.

Simply increasing the damage done, long combat penalties, or insta-kills are all mechanics used to prevent a party from carrying especially bad players. They punish the party as a whole to significant degrees, and even more to healers who have to bear the brunt of dealing with these punishments. I'm trying to isolate the punishment to the offender, and limit the affect to the rest of the party. That's why I liked the reduction to drop rolls idea.

Everything else I said was just pointing at examples that SE actually put into the game, which in my opinion, was an attempt to punish bad players. I think most of them end up punishing other members of the party to a significant degree though, which is what I'm against.
