TheSword
Legend
This is more for a campaign set in a largely human city.Because you can play as other races, the result is that everyone wants to play anything other than humans, so why should so much work be done for a "monster" that you may never encounter?
Humans will always be comparatively weak to dwarves, elves, orcs, and aaracockra, and this largely has to do with a rejection of the race-as-class mechanics of older editions. The newer rules have to be written to reflect this, and now anyone will look at a human and think "vanilla."
You could restrict playable races in your campaigns, but will get you sour looks, or you can desperately try to make humans more interesting, which is still plausible.
Or, follow the money and just write humans out of the game instead. This is far easier, and no one will really complain.
For PCs, I actually see a lot of people playing humans because of the additional feat and skill. They have been competitive for quite a while.
