I don’t feel like half-elves bring much of anything to the table. I feel like Aragorn is the only reason they are even in the rules in the first place, but with that being said I don’t know that I have ever seen anyone play a half-elven ranger. In most cases you’d be better off being a whole-elf ranger instead, and I’ve seen a lot of those. In my experience, the only time half-elves are ever played is if someone wants to play some odd multi-class combination, like a fighter/magic-user/priest. And in those cases, the player wants to play that class combination first and foremost; being a half-elf just happens to be the only way they can do that.
I mean, I suppose half-elven characters could be interesting, I just haven’t seen it. I don’t feel like they really suffer from the “rejected by both races” stigma that is given some lip-service in the racial description and I feel like anyone that claims they do probably shouldn’t make those claims around any half-orcs.
However, my problem with half-elves may not be all their fault. I feel like these guys were just shoe-horned into the rules because they existed in popular literature. I just don’t feel like they were given much of an identity in the process. I wish I had something more to say about half-elves, but I really don’t.
So yeah. If you want to play some combination of a magic-user/priest/something then you should play a half-elf, because you don’t have a choice.
Maybe you love half-elves and play them all the time. Maybe in your campaign world you have woven the story of the half-elf into a rich and vibrant tapestry. That’s great. I’m not trying to offend anyone, I’m just talking about my experiences, and I would love to read about yours.
