Being a mace specialized character, it's a bit annoying seeing such a small amount of them.
It's something I get reminded of every time the game throws another sword my way, like becoming a thane of a hold always seems to end me up with another bladed weapon as a reward.
I was recently able to pick from a variety of Skyforge Steel weapons for a reward as well, and there were no mace (or warhammer) to pick from.
The same holds true for unique weapons, swords and axes dominate here too.

There is also no mace or warhammer weapons in these materials: Silver, Falmer, Ancient Nord, Forsworn, Nord Hero.

At least artifacts don't disappoint too badly with the Mace of Molag Bal and Volendrung to select from, but overall swords seem to get the advantage.

Yeah, I wonder why maces have less options than axes and blade.

There are no more "blunt" weapons. There are only one and two handed weapons. After all, everyone knows there's no real difference between a mace and a katana anyways.

Yes, but luckily the smiths have began to maek more diferense between them.
