Until I actually play any of the three Dragon Delves adventures that were listed as possible for solo play as a solo play player to see how their solo play rule suggestions actually work... I will not bother trying to "fix" them sight-unseen. Heck, for all we know a veteran D&D player could...
And the answer to this is that they should be in any specific 5E24 game if that game's DM wants them to be and makes/finds a Half-Elf species design to incorporate into it. If specific Half-Elf game mechanics are that important to that DM, then that DM can add them.
But if the question is...
That's not the point. The point is Vex and Vax could have been half-elves in CR Season 1 and been played as half-elves and been treated as half-elves... even if the couple of racial game mechanics written on their character sheets were human ones or elf ones. You don't need specific game...
Could be done, but never going to be done. At least not within the 5E paradigm.
The D&D advancement game is about Class. That's it. Class is all that matters. Species, background, feats-- all minor flavor bits by comparison.
They all stink and do not identify a gosh-darned thing.
BA Dash? Is it an orc or a rogue or monk? I guess this ability insinuates they are one and the same.
Perception skill proficiency? Is it an elf or pretty much any other character that selects the most popular skill in the game? The...
I'd let you use an Unseen Servant in this way even if there weren't "rules" in place to allow it. In fact, the Servant wouldn't even be just barely passable, but actually a fairly good drummer at the beginning. And as the Bard leveled, the Servant would level up their drumming skill too...
I for one do not find a single species whose mechanics are appreciably meaningful... especially not when you bury them under 20 levels worth of class mechanics. ;)
## What's the matter with the game I'm playing?
## Can't you tell when I roll my dice?
## Maybe I should buy some new d20s
## Or will my dice pool mechanic suffice?
## Where have you been using Foundry or Roll20?
## You can't get a mini without spending lots of money
## Everybody's talkin'...
Exactly. If (general) you want your PC's history to include the fact that one parent was an elf and the other was a human... that's fine by me. Your backstory is your backstory. But I wouldn't have (general) you use special game mechanics to represent it. There aren't any special mechanics...
I still don't get why some people feel it is so important to think that "Pathfinder outsold D&D" or that "Daggerheart will surpass D&D" that they'll go through all this effort to try and claim/prove it.
If (general) you have such an issue with the idea that a game you do not like is the more...
Well of course. But I was referencing the comment that implied that due to people being laid off in America that we were heading to a dystopia.
But then again... if things are bad in other parts of the globe compared to America... those places are still better now than they were during First...
