I'm not satisfied.
Start characters at 3rd level?
Start the campaign with fewer fights?
I don't understand. Do your 1st level monsters need a natural 19 or 20 to hit?
I'm not making any exceptions for wizards in the back who get shot in the eye with a crossbow bolt. They are dead.
First level characters are not novices. They have become adventurers because they've got something more than your average non-player character.
I'm not saying they aren't more. I'm saying they are not enough. And if they do die so soon, it could be just as the DM's fault(when he presents them with an encounter that is unsolvable at said level by the group's standards) as the player's(who Leeroy right into an otherwise easy encounter, then whine if they are riddled with javelins). Or maybe, just maybe, they died because dung happens. What is there to complain about, exactly?
A point you're missing is that most NPCs are worse than the players already. And I say
most because nobody stops the DM to throw an optimized character with PC classes in your face that one-hit kills an optimized wizard of the same level, just as you could play a Commoner with the Chicken-Infested Flaw or an Adept with support spells only. PCs are better because they are controlled by players. That makes them special, not class abilities, feats, and especially not a ton of hit points you want to give them because you can't handle the fact you can fall over dead exactly as easily like any other living being, and the universe doesn't bend to your will by making you double as though as someone of your class, NPC or not, is otherwise supposed to be. Where would they get those hps anyway? Do you just say '
they are the goddamn PCs' and be done with it? That makes a hilariously good joke, but people might look weird at you after they realize you're serious.
I need a constant factor to design games.
You need more practice, then.
I liked 4th edition because I roughly knew how many hit points the party had and how much damage they could take before I had to scale down the challenges. I think that when 5th edition comes out I'm going to give all the players the option of having static hit points added to their constitution scores at 1st level or let players such as yourselves roll 1 hit die.
Well, nothing keeps you from playing 4th edition. There is nothing bad with playing what you like, and I'm sure you'll find people who share your opinion on hit points as well, if you'd rather "upgrade" to 5th ed. I remember how many whiners where around back then at the dawn of 4th ed to whom never occured that with a new release, not a goddamn frickin' thing changes. Don't be one of them. People play the Edition they like more, changing sides is not a necessity. Newer Editions are never 'better' than the last one, they are different, with a different target audience. The Wizards' main directive is money, and nothing in the D&D franchise beats the millions of dollars Magic:the Gathering drops into their pockets. The chance somebody will care what complaints we have as individuals is microscopic, so you'd have to invest your all of your time into grabbing their attention and convincing them, which, in the end, wouldn't really amount to anything. Don't waste your life on this argument, you and your pockets are better off playing whatever edition you prefer and houseruling it to your heart's content.
