I was curious as to why we can't roll for stats. It has been a mainstay of creation of characters since 1st ed. I feel it Grants too many benefits to deny. If you have a high stat, your not the cookie cutter average being of said race. If you rolled a low stat, that is great also, because now you have to roleplay (darn). Having stats that are within similar ranges causes that not so unique feeling a tad more in my opinion. I didn't see in the previous pages her anyone bring this up. In a world(s) of magic being able to have higher and lower variables creates better rp effects. IMO
Standardization for characters at first level is really one of the few constants in the Multiverse, and as much as I love leaving things open for DMs to add their own twists to things, I'd advocate for keeping 1L character creation to Point Buy and Standard Array only.
Besides, I can just see players rolling new characters again and again and again until they get a pool of 15+ rolls for every stat, and there really isn't any way to regulate or prevent that sort of thing.
