Umm, what? A glass cannon doesn't mean what you think it means. If the creature either kills a PC or dies without being any real threat to the party, that's a glass cannon. It has nothing to do with the PC's.
Sure. Apparently, if the creature doesn't get to kill a PC because the melee specialists dispatch with it in 2 rounds because they are pimped out with ability buffs, damage buffs and AC buffs, that's different from a creature that doesn't get to kill a PC because the knowledge specialists have determined its weakness beforehand, prepared the melee specialists accordingly, and they get to dispatch with the creature in 2 rounds. The latter, according to you, is a glass cannon. What's the former called again?
Again, what CR is a group of 5 creatures that has a 66% chance of killing one 20th level PC?
Now, we have claims that CR doesn't work. Well, that might be your opinion, it certainly isn't mine. I've found that CR does work. Not all the time, certainly, but, it does work when you realize its limitations. I'm not saying CR is perfect. Far from it. A CR 13 encounter of stock goblins is a joke. Of course, the CR system SPECIFICALLY STATES that it can't calculate this as well. Pretty hard to talk about a failing when the failing is deliberately called out in the rules.
You know, that's two completely different failures we're talking here. Me, I'm simply claiming that CR as the sole arbiter of a creature's difficulty in an encounter is insufficient. That has nothing to do with the designers noting that "Hey, this CR for one creature is fine, but it might get very wonky if you scale the CR of them up through sheer numbers." Apples and oranges, you know.
But, Mustrum Ridcully has hit it nicely on the head. If a rule requires special tap dancing by the DM to work, is it a good rule? Is a monster that requires all sorts of fiddly bits in order to bring it back in line with its expected challenge well designed?
IMO, no. A monster should be usable out of the box. I shouldn't have to do all sorts of extra work in order to use a monster. If the monster has a specific location requirement (like a shark for instance), I shouldn't also have to make sure that the water is 72 degrees, there is a slight chop and overcast sky as well in order to use it.
Agreed...this simply means that there should be a better system in place to adjudicate monsters. CR is simply not enough. It probably works well with straight melee monsters, but as soon as the monster in question has more than one special ability that doesn't directly map to combat damage (hit points), CR goes down the drain more often than not.
But hey, we could of course simply start cutting away all abilities that do not map directly to combat.
Now, if I want to add in the extra effort and reward players for being smart, that should be up to me. The rules shouldn't force me to do all this extra work, just to make up for faulty mechanics. Fix the mechanics in the first place and we're good. Like in the demon cult example I posted a bit back. If I drop hints that there really is a demon up there and the party prepares for that, by all means they should be rewarded.
However, I don't believe that the reward should be an anticlimactic encounter where the party slaps the monster around like a rag doll. Even the party armed with cold iron weapons and a Dimensional Lock spell still has to deal with that Glabrezu - no mean feat. The party that slaps on slow poison and protection from petrification walks up to the medusa and noogies her for fun.
Wow, great encounter.
Yeah...and a 13th level group that confronts a Glabrezu with nothing but cold iron weapons and a
Dimensional Lock either has a very stingy DM, doesn't have a clue about what a Glabrezu really can do, or is desperately looking for a TPK. If you have a "standard" 13th level group with standard equipment with proper preparations, they will turn your Glabrezu example into a 2-round battle. I can only refer to the
Tales of Wyre story hour to illustrate what a really high-level group that prepares for an encounter does to the monster in question.
At some level, preparation turns every monster into a cakewalk. Which is why people prepare for encounters, if they can. To minimize, or negate, losses while maximizing their kill probability.
The bigger problem is that CR is simply not the be-all end-all of monster classification. It's good at giving pointers, but designing everything around it, or demanding everything should fit it is a bit short-sighted, and shows in many cases. RC already said it...CR discussions are nearly as old as 3E itself.
