I hate gnomes.
Not the race themselves.
But the way D&D have dealt with them.
In 5th edition there are two versions: forest gnomes and rock gnomes (which are basically tinker gnomes).
I dislike both of these subtypes.
But, it’s not just the subtypes I dislike – there is a larger issue here.
D&D has never really decided where gnomes fit in.
And this issue has been prevalent throughout all editions of D&D, so I am not picking on 5th edition here.
