I like the black and white colours the most, but that's mainly because the colour is more solid on them and doesn't have those noticeable bald spots. If they brown or grey didn't have those bald spots I'd pick them because I'd prefer a brown or a grey over white or black.

Hi, me again.

So, I just got another idea that clamped on to my brain and hasn't let go: Yes, we should totally get werewolf colors, and at least the three currently-playable colors should be added for free.

but... what about swapping the werewolf model?

The lorebook On Lycanthropy talks about the other werecreatures in Tamriel. Granted, werecrocodiles, -lions, -vultures, and -sharks have only really been mentioned this once in this one lorebook (that has existed in TES lore since Daggerfall though). We do currently have werebats in ESO, but they're really just renamed Giant Bats and there's not really much information surrounding them otherwise. But apart from the ubiquitous werewolves, two other wereforms have made more impressive appearances in the TES series.

Daggerfall had playable wereboars. In fact, they exist at a higher level than wolves and the user guide says that wereboars are actually the more fearsome opponent.

Skyrim's Dragonborn DLC also gave us werebears. Players couldn't be a werebear without mods (and you know right away that those exist!), but we did also have some quests involving them as well.

So yeah, as much as I want to get the three basegame colors for my werewolves, what I really want is the ability to be a different were form. Sure, it'd just be a model swap and would still be called the "werewolf" skill line with pounce attacks that may not be wholly appropriate, but I don't care about that.

ZOS, I would pay an inordinate amount of money for this:

A brown werebear skill style. Just take my money. Name any price. Please.
