I think that’s a fair question. There really isn’t much reason to not let the player use things that you’ve already modeled and that work with the body form.
My “no one” in that context wasn’t intended to be an absolute. There’s always going to be someone (or more likely, many someones) using a particular item or doing a particular thing in a large population - my use of the phrase was more about the size of the constituency relative to the larger population playing the game. Again - I don’t have the data so I could be totally wrong, but it’s almost certainly the case that Bamco is using the player usage data available to them to prioritize their DLC on the accessory side. They want to sell us things, and that means they want to put things in there that large numbers of the playerbase will want to pay for. Could be that lizardmen are super popular offline (or even online, and I just missed them all), in which case Bamco will certainly want to add them in there. Could be the other way though, which means they won’t be in any hurry.
