I can understand where this player's confusion/complaint is coming from, though. I've played a half-drow warrior with wisdom as the primary statistic once (quite) a while ago, and often found myself wondering the same.

What this basically comes down to in my opinion is the number of consistency issues that seem to arise from the current set-up regarding half-elves, and to a lesser extent half-drows, and their primary statistics. The most common of these issues, as the original poster pointed out, is a half-human's ability to reach a wisdom which neither type of parent inherently is able to. Given the rationale behind a half-elf with a dexterity primary who will then reach a number of 23 at best in that statistic, you'd thus expect a half-human choosing wisdom as his primary to receive a 23 wisdom and have the remaining point flow into another stat just the same.

One other thing regarding half-elven characters is the removal of their ability to reach a 24 dexterity, as under the current set-up this tends to result in a perceived limitation for a player who intends to have the character actually be of wood-elven lineage, rather than of high-elven. Naturally (no pun intended), one would expect a half wood-elven character like this to have the option/be able to reach a dexterity of 24 for the same reasons a half-drow can. And conversely, a half-elf who is partially of a wood-elven lineage would have little business achieving a 24 intelligence either as they are currently able to, even when/if roleplayed as a half wood-elven character. Quite a hassle really, especially if you're not too familiar with the effects the character's age has on its stats for whatever reason.

I'll agree that this isn't worth creating a seperate sub-race for in a similar fashion to how the distinction between half-elf and half-drow originally was made. Indeed, that would potentially make CF drift in the direction of MUDs where humanity has managed to mix itself with virtually everything bar things that sprout tentacles (and then some). But on the other hand, it might be quite an interesting new feature to give a player who chooses half-elf for a race a choice at character creation between this character being partially of high-elven heritage or wood-elven heritage, and then have their statistical make-up correspond to that choice accordingly. E.g.; you choose 'half-elf' as your race, and receive as your next question: "Are you of high-elven or of wood-elven lineage?", just to give one very bland example.

From a practical point of view, I'd say this would come down to the following;

1) a half high-elf with dexterity as primary statistic achieves 23 dex and has the remaining point allocated to the strength stat as is the case already.
2) a half high-elf with intelligence as his or her primary achieves 24 intelligence just the same.
3) a half wood-elf with dexterity as the primary stat achieves 24 dexterity.
4) a half wood-elf with intelligence as the primary statistic achieves 23 intelligence and has the remaining point allocated to wisdom, resulting in 23 int / 22 wis.
5) all types of half-elf that choose wisdom as their primary stat receive 23 wisdom and have the remaining point allocated to intelligence, resulting in 22 int / 23 wis.

Be warned that all the above is the result of some early morning brainstorming however, so feel free to ignore as needed.
