Even if it is FR specific, all you have to do is change some names and minor details and you can generally plug whatever it is into any setting you want.
And I would argue that the ruleset has nothing to do with preventing bad players from derailing a game. That sort of behavior and curtailing it is a social issue that is handled outside of the game. The same with bad DMs. You can't make rules that take care of or prevent either problem.
You can also tell that it's just a marketing ploy by the amount of "playtest" time they give. The questionnaire comes out like a week or two after the document is released, which isn't anywhere near enough time to have any kind of quality playtest for the class(levels 1-20), subclasses, and...
There are a number of rules and decisions in 5.5e that as written leave me underwhelmed by the ability of said "professionals." The hide mechanics and the organization of the MM to name two off the top of my head.
I think fewer of us would think we could do as good a job or better if they took...
Ha ha, but no. A druid isn't doing rogue things and fighter things, intruding on their niches by default. It's a deliberate choice the player makes to do something like that.
Again, this is not about power disparity which is a completely different issue. Power disparity cannot invalidate...
Try again. I said several posts prior to that that DMs create the problem by enabling through just shutting down the world. They can play however they like, but if they create the problem, they shouldn't complain about it.
I'm talking about class niches, not power levels. If you have a wizard and a cleric casting Knock, Find Traps, etc. instead of letting the rogue do it, they're being douches. Power level is a completely different issue and is only broken if you feel that it is.
I played a ton of fighters and...
If the player of the caster is being "merciful" by not invalidating another player's character, that person is an ass and should be kicked out of the game immediately. By "thoughtful" I meant considerate of the other players. Anyone who isn't "thoughtful" in that context doesn't deserve a spot...
