- Hit Dice-Have no apparent purpose
- No called shots? Grapple? Critical Hits?
- Baby Goblins have full HP?
- No way to identify magic items.
- "We have enough problems with innumeracy in this world for you to make the math in the game stupid or to make numbers not count."
As a DM, I have a problem with this. We use an elegant critical hit and fumble table for our campaign, there is about a 1% chance of injuring the party and a <1% chance of automatically killing. The player rolls the percentiles, knows high is better (or worse for fumbles) and the DM modifies the result as needed for the situation. This critical hit and fumble chart is older than 80% of the players at the table, btw.
Grapple, however, is very important. It could be resolved using non-lethal damage, but, frankly, grappling someone and knocking them out are different. We use them for different things. I appreciate that the rules for #DnDNext seem to be about the players succeeding as much as possible, but frankly, a non-lethal attack, especially with a weapon, should always be dangerous for the victim. Yes, there is a possibility you kill the guy you're trying to knock out!
Baby Goblins have full HP: Because we were "playing as written," the immature goblins had 5 hp. Because all goblins in the universe do, unless they are chieftains or specially declared goblins. Did I mention that I, as a DM, found this a dumb thing? Because if you have a herd of antelope, some of them are sickly, and if you are the lion, you go for the sickly one.... but, anyways, those are for a different installment.
Here are the magic problems we had:
Sleep: THE MOST POWERFUL SPELL IN THE UNIVERSE.
Instead of being hit-dice based, sleep is now an area effect. A 20ft radius circle area effect. Here is your circle on a map showing 10ft squares. To make it even clearer, I've drawn a radius. To make it clear even to people who are dumb, I've also drawn a diameter.
Now, I want you to picture something, for a moment.
You have a room full of goblins. There are, in fact, about 30 of them, depending on how many have run in from other rooms at the thought of their offspring being killed and knowing the party is around. Thirty small-sized beasties. If you are being parsimonious, you may decide that each size small creature takes up 1/4 of a square. The general rule in the past with such things is that a critter as small as a goblin, rushing you, crowding in, can be as high as 8 in a square, but let's allow the game to be fairer, and let's say the goblins space themselves about equidistant on the map, and in the 6 squares that are mostly in the map, either 3 or 4 goblins fit, and in the 6 squares that are mostly off of the map, you only hit one. This, again, is being overly parsimonious, in that the sand from the wizard's spell doesn't need to cover you to affect you (again, playing as written) you just need to get hit with it, which includes everyone in this circle. So, what does our wizard do with the 30 goblins?
The same thing she'd do with 48-50:
But that's just your sleep! You also have six at-will spells. And that's why, when the party discovers it can take on just about any horde and goes after a boss with no planning and no healing left, allowing boss to get the jump on them, YOU and the rogue are the last two characters standing.
CONGRATULATIONS, WIZARD! You are now a tank. You will have no trouble soloing act one of Diablo...oh, wait, this isn't Diablo, this is a group game, and you've been upgraded to the point where you are impossible to kill and as long as you keep backing up, never out of ammo. It's like having a bow and an ever-full quiver, only your arm never gets tired, and you don't need to aim.
