The video for those who are curious. Absolutely worth the 20 minutes.
I got around this by being a Path of the Beast Barbarian Dragonborn. I was a Weredragon and when I Raged I became more dragon like. I almost exclusively used the tail function for the shield reaction while still messing people up with a Magic Maul.
You want a tail, play a Kobold!
This only became an issue when we defeated a half dragon non-lethally and the DM was making small talk with the dragonborn.
Canon is wrong, dragonborn have tails
the official canon states that tieflings can't be purple, and yet the official artwork for a tiefling is a purple tiefling
Possibly the most ignored sentence in the PHB, even by Wotc themselves:
Official Dragonborn PHB description say Dragonborns are brown/rust coloured, with some being rust-copper green.
Artwork on the same page is a red scaled dragonborn.
