It had been pointed out in the past that Metamagic was synergistic with the 3.5 Sorcerer's known-spell restrictions, and fit with it's innate-magic concept, and that it was unfortunate that the class had been made mechanically inferior to the wizard in gaining and applying metamagic. So, yeah, there was wiff of it. Not in the playtest, but if you went far enough back, it was well-articulated minority opinion, like, way back when, on the WotC Gleemax boards.As I said, this is much easier to say in retrospect since the classes are printed in 5e so we can look at concrete mechanics. But would metamagic/sorcery points had been what people thought is what makes the sorcerer the sorcerer prior to its printing in 5e?
Sorcery points, OTOH, no, whole cloth, something slightly original, even - though much less evocative of the Sorcerer's nominal "magic in the blood" concept, than the morphing playtest version. ...hmm... OK, there might have been suggestions the Sorcerer could/should use a mana system, at some point. There were certainly, early on in 3.0, some folks pointing out that there were plenty of spell-point systems back in the day that could have been adapted to the sorcerer instead of or in addition to spontaneous casting.
Hold psionics to the same standards as arcane casters were apparently held, and there should be two or three psionic classes in the PH.Yeah, with differences like these, I think that nearly any psion class could be justified.
Yes. Which is why you're being asked for mechanical differentiation.Seems like psionics would qualify for 5e's "concept-first class design" quite well.
Similarly, if there's a very clear implementation for the class, it's "too narrow/classes need to have at least 4/6/10 sub-classes," while, conversely, if there are many potential takes on the class it's "too unfocused/no one can agree on what it should look like."
Also similarly, before you can ask for the class, you must build the class, and once you have built the class, you don't need the official class, so shouldn't ask for it. Also, you can only want what WotC decides to give you, otherwise you're just in a tiny, vocal, minority who selfishly wants something unpopular. Until WotC does put the thing you want in print, then you're in the well-served majority who wanted it all along, because it's always been popular.
Because that's what passes for reasonable discussion around here.
