That's a problem that's plagued WotC D&D since the earliest days of 4e: violently shoving legacy ideas into the immutable structure of the new rules, into conceptual spaces that they simply do not fit into, with no regard for the core fiction of those concepts. Warlock Templars in Dark Sun, really most of the races in Dark Sun, the incompatibility of even basic character archetypes from edition to edition (even going back to 3.0), and just so so much of 5e... the reskinning philosophy and methodology has completely divorced the sacred mechanics from all the worthless fluff.Other great examples: Early on, the designers were in fact explicitly in favor of "martial healing," and Mearls himself tweeted that if folks didn't like martial healing, they could just choose not to play that type of Fighter (or choose not to permit it in their games, for DMs.) But because they were so adamantly against including an actual Warlord class (even though the Warlord was, by their own polls, more popular than Druid!), they had to find a way to squeeze all of that into the Fighter class.
I'm not even sure I can blame Wizards of the Coast for this, because if this wasn't what the fanbase actually wanted, it's certainly what they've demanded time and time again.
Wow. What an epic Necro, past me gives me cringe.
Think ten years is bad, try using the forum search to look for specific homebrew or campaign ideas, and the only result you get is your own self, asking the same damn questions back when this was Eric Noah's D&D news website.
