Strange, I feel as if have seen this before... Is it a psychlogical deja-vu, or was this posted before?
True. I've played D&D for decades and Gnomes and Half Orcs are rarely played. In fact, the stress on Strength as "teh best stat evar" for 3e made pure Orcs more popular that either combined for that edition.Now that [gnomes and half-orcs] are gone, there's no reason to hate on them. So the haters are quiet, while the people who loved them are noisy.
I like both the tiefling and the dragonborn. My only beefs with them are art-related only ... I hate the tieflings' massive horns and ridiculous crocodile tails, and I'm not sure about dragonborn boobs, but other than, they're cool. No issues.
