I mean, I get it. The issue with that term is that it confuses what "challenge" is in the context of this game.
Meh. 5e brought back CR. The C in CR is for 'Challenge.' A higher CR means a lot more hps, more damage, and slightly higher bonuses, all to make it challenging to higher level characters.
Sounds like a fair use, to me.
And that's a very fundamental concept in my opinion, something all DMs need to learn (among other things) but
very few in my experience seem to understand.
Sounds like a topic for another thread, entirely. But, if explaining that concept is important to you, maybe try explaining it rather than attacking a tangentially related idea for the label used to express it?
It's not hard to remove the challenge at all, in terms of challenge that happens during game play.
So, you're asserting that system mastery, for instance, only exists at chargen? Certainly it's most notorious abuses do, but it also matters in play. Player skills & player choices vs DM challenges, in play, still, it seems.
All you need to do is remove the need for a player to apply skill to overcoming the challenge. Rolling a die isn't skillful. Coming up with the action that will net you automatic success or at least allow you to roll for a chance at success is skillful.
Coming up with the action that will let you roll a skill your character is good at is also applying player skill to a player choice to overcome a challenge. It's just an instance that takes the character's capabilities into account, and contributes to RPing the character concept.
If you could find posts of mine from the WotC forums, you will most certainly find me saying stuff like "challenge the characters," which was a common thing to say when D&D 4e was the current edition. I have since learned that it's not a thing.
...
As for reading, manipulating, or gaming the DM, you would also find me arguing that point in old forum posts as I railed against "DM Empowerment." I have since learned that these are acts of bad faith on the part of the player and the response to that is not to play with people who act in bad faith rather than go to the mechanics to help deal with it.
So the editions changed and your standards changed with them. :shrug:
'Gaming the DM' is not bad faith, it's inevitable, that's just part of how humans interact with eachother. Not always to the degree of being cynical/cruel/unfair about it, of course.
It'd probably be a bigger issue if the stereotypical D&Der were better at it... ;P
The balance issue isn't that it's wrong to game the DM (on the players' parts), it's that it favors some players over others, and doesn't model the characters being played. Much like system mastery rewards being too great. It's OK for some players to be system-masters and some 'master'-manipulators, it's not so OK if either or both reap too disproportionate a benefit, to the point of imbalancing the game and ruining it for others.
