There are several different races in the game. Humans, Abysians, Pangaean halfmen, Atlanteans, Vanir, Jotun giants and so forth.

Different races tend to have different lifespans, and for humans, old age hits at 50 unless they have nature magic. The Avalon Crones are humans with powerful nature magic, but even so, they have far outlived their normal (augmented) lifespan, whereas the Vanir and Sidhe count their lives in centuries. They this have more time in which to learn things and consequently do not start out as old comparatively.

Some of the old age mechanic is also a balance effect or otherwise all the powerful mages would stay around forever like they did in Dom2. The aging mechanics also force people to make choices between scales, or otherwise we would see nearly everyone using Death 3 for free pretender points.

Those who do not wish to deal with the aging mechanics are free to do their own mods. Frankly, and this is a general statement not aimed at anyone in particular, this demanding new features every time something isn't tailor-made to suit a particular player's PREFERENCES is starting to grate.

There's also the issue of priorities. The devs only have a limited amount of time they will use on Dom3 and assuming they would be equally interested in doing any of the following -
a) bug fixes
b) new content
c) tinkering with a feature to modify things that are not broken (but could easily become so) and which were intended to be in the game in order to accommodate people who could, with rather bloody minimal effort, do away with it for themselves.

- you can basically pick two. My picks are obviously a and b. That's with the assumption that the devs would consider all equally weighty things, and, my personal guesswork as it may be, I don't think they put as much weight on c as they do on the others.
