Are they? Who decided that? And when? Artificially isolating one specific aspect of play, when comparing characters, invalidates any perceived values you may be trying to identify. At least AFAIC.
I mean, when we do stuff like that we end up with similar *facts* like, "The barbarian is clearly the weakest class." Because we happened to be measuring spellcasting potential at the time.
. . . The discussion I'm having with Cyrinishad. He claimed that the damage optimised ranged build was being compared with a sub-optimal melee build. I asked for a better melee build that would make a fairer comparison.
As I pointed out in the post you quoted, there are other aspects of the game, but neither ranged nor melee builds are superior at them inherently. (Or equivalent. For example the ranged build is better at stealth than the melee build, but the melee build is better at climbing etc.)
All other things being equal, you
can directly compare the combat performance of two different builds by their survivability and damage output.
So: what things do you believe are not equal?
I think this sums up are crucial difference in our perspective, in that I think that these roles are not outside the scope of this discussion... If those other roles did not exist, and the game were entirely a DPR calculation then I might concede to the assertions made by the OP and the "Ranged>Melee" crowd. However, all of these things are part of what a melee character does. Therefore they are a necessary part of determining the efficacy of Melee combat when compared to Ranged combat. Especially when all of those things are built into the current Fighter class (otherwise known as the "Melee" class).
To point it out to you again, currently
both the melee and the ranged DPR specialists that we are directly comparing are Fighters. Fighter is not "the melee class": there are classes much more focused on melee. Several of the Fighter archetypes are either pretty neutral either way, or outright ranged-focused indeed.
Now currently as far as I'm aware we are still discussing the two damage-focused builds: The ranged one put forward by the pro-ranged crowd, and the build that we are waiting for you to put forward since you feel the melee damage build currently being discussed is sub-optimal.
I'm quite happy to have another discussion with you regarding the other roles. Which ones do you feel are "part of what a melee character does" that are not also part of what a ranged character does?
