This is a complete lack of imagination, and actually proves the point you were debating by
@Lyxen .
I had a 5e half-orc wizard. He was phenomenal. Maybe my favorite character to date for 5e. He had strength, and I could occasionally smack things when they got close. He had athletic ability. So when it came time to climb, jump, swim, lift, etc. I didn't worry. He would get dropped and bounce right back up. He could intimidate. All these things made me play the wizard differently than I would have if I had played an elf. And guess what, he was smart. 15 smart. So better than most.
So he had a niche. You just don't see it or you think the only niche there is is to start with a 16.
