As the GM, I don’t really have that moment of anxiety when it’s time to roll for hit points on a level-up. That one roll can be make or break for a character. If you’re playing strictly to the rules (or in Nightmare mode), a few 1’s for a couple of levels can doom your character. So the question is, is there really any good reason to be doing this?
I know that some people like the randomization that comes with rolling your stats. There main philosophies boil down to:
1. Total Point Buy is as even as it can get. You get full customization options and you’re never left behind. This is the character-first method.
2. Rolling a character helps you build a character organically. You create a character from what you’re given, rather than from some starting concept. This is the stats first method. A subset of this method believes that you should generate scores completely randomly, where the averages make you a normal person, so that you can start from humble beginnings or overcome serious deficiencies.
