This seems a really deeply felt response, and I find it surprising. Which Dragonmarks do you find more powerful than, say, Magic Initiate (Wizard)? Find Familiar, True Strike, and another wizard cantrip, cast with Int, Wis, or Cha, seems to me a high benchmark that (arguably) none of the Dragonmark feats match in terms of power.I'd never allow 2024 Dragonmarks in any other setting.
The 2014 version of them was reasonable enough to include as options in other settings, but the 2024 Dragonmark feats exist to make characters who choose them much more powerful than any other characters. I'd have no intentions of being unfair to players who don't pick balance-breaking options to let another player get significant expansions to their spell list, or feats that are stronger than everyone else's origin feats, or even get extra casts of much more powerful spells than anyone else can acquire via feats.
And there you have an example of what I was suggesting for Dragonmarks -- make them important and lore-connected in your setting.Though that doesn't mean the only way to introduce Warforged is like this.
I like the idea of them being a Dwarven creation. In one variant, Warforged are a way for couples that can't have children (maybe due to a disease that lowers fertility, homosexual pairings or multi-racial pairings ) to create something like a child. Two souls merge and create a new soul, just like in biological procreation, but the result isn't a dwarf, it's a construct. This would be very different than Eberron Warforged - these Warforged might have loving parents actually, and grew up in the Dwarven culture, maybe the culture still treates you different from normal children (and children treat you differently).
The point isn't just removing it from it's original lore. It's taking it from it's original lore solely for it's mechanical aspects without replacing the lore, like the Forgotten Realms and some other kitchen-sink settings have done with the Warforged.I see your point, but to me, it is still a mechanically interesting option to model some of the scenarios described in my initial post, even when you remove it from this original lore.
For my personal version of Eberron, I split the difference. The majority of Dragonmarks are passed on via familial/"genetic" lines, but there are enough spontaneous marks that a PC of a different-than-expected race won't be some massively weird outlier. Most Houses are between 90-95% made up of the "standard" race.If I were to use them in another setting, the first thing i would do is completely disentangle them from ancestry. I have even considered doing that in Eberron -- I think the Houses might be more interesting if they were built around the Marks first, and not race. But that would require a lot of lore revisions I am not especially interested in doing.
