It's funny how people say if I roll a "1" and die that is "unfun"? If the only way you are going to die is on a "1", which means the only way your going to fail a save is on a "1" then I wonder why your playing? As stated this game is about heroic adventurers, going out and slaying creatures and evil people! Even in the movies the hero dies! So if you take out the auto fail on a "1", and also take out the Save or die spells, why even have spells? What is the point of adventuring?
Just get a big nurf bat and hit goffers on the head? No threat of dying there?
Yes not all game players like it the same, but some of us like the Threat of being able to have our characters face potential death when a powerful demon (or wizard) points his finger at you and calls up the infernal abyss to consume your soul in a powerful strike? You had better be one lucky soul to live through that. Now should that demon (or wizard) be able to do that every round, well maybe, but as a DM, I don't think most I know would do that even if the creature could. If it could I would have to question, why I was going up against it so ill'prepared. And if I was, then yes I would probably expect several of us to die...
But I would never classify it as unfun, that is the great adventure to slay the great demon lord!
Grappling, funny, in 1st Ed, there were few if any rules, the DM just winged it, and had you make a d20 check either based on THAC0 or a stat to see if you succeeded, now we actually have a set of rules. If you have a cheatsheet or custom character sheet rather than one of those cheap things WoTC gives you, you would have the formulas you need next to the types of attacks your characters make, thus its a non-issue. As a GM if I select a monster for an encounter that has Improved Grapple, I'm for sure going to look up the rule prior to the session and make sure it's on my cheat sheet so I don't slow down my players fun time.
If WoTC did their homework proper and created modules right, when they created a monster in the first place, they would put in the entry with a monster the rule for grapple next to the encounter area (or in a side bar).
I will admit not everything is 100% fluid, but I wouldn't call it unfun, otherwise I wouldn't be still playing, though in looking at the rulings that are coming for 4e, I am not happy, but I will hold my judgement.
