What works for M:tG isn't necessarily going to map equally well to D&D, because one is a hugely abstracted card game with flavour as...well, flavour...and the other is a very specific fantasy world simulation, with flavour as one of the main reasons for bothering to play in the first place.
D&D is, and has always been, a highly abstracted game. That's why things like AC, hit points, and most of the mechanics do not map cleanly to real world traits, since they are an abstraction whose purpose it is to prevent simulation of things to slow to a crawl.
But the temptation to create mechanics for mechanic's sake, resulting in abominations with no flavour reason for existing, like the "warlord", is seemingly too strong.
Ah yes, the idea that a martial commander who is more adept at leading troops then just beating ass has no right existing in a game that features a guy singing while his friends fight a dragon rears it's head again. Sorry rounser, but a game that features giant, acidic Jell-O molds as enemies is not negatively impacted in any way by having a battlefield commander when having a opera diva as your support in combat is acceptable.
It's D&D, and we see silly rules that don't make sense except for extensive handwaving and references to Die Hard.
Yeah, silly rules like hit points and AC and levels, all of which are huge abstractions to avoid issues like infection, hit location, and the like.
It's all so ideologically extreme, like the result of giving an extremist political party dictatorship powers, and seeing the unexpected side effect result of their ideologies come into play.
Comparing people who reduce liberties, impose sanctions, and take lives to the developers of a roleplaying game is so beyond ridiculous it approaches insanity.
Maybe D&D will become more like M:tG (or already has become that way), in that people will take their Dragonborn for the +2 strength modifier just the way they'd put a Derelor in their deck for being a cheap casting cost 4/4, and just think about the crunch effect...stuff the flavour.
Oh, just like how people back in 1e and 2e would take "elf" or "dwarf" for the bonus to Dexterity and Constitution. This attempt to paint the newest editions as the only ones to attract power gamers is silly, since history demonstrates the game's ability to attract gamers that only pay attention to the crunch from the outset.
Arguably it's already begun with 3E and it's "builds". They harken to M:tG deck construction.
Or they harken back to spellbook construction in all previous editions of D&D, since two wizard builds can be entirely different based on the spells they have selected
