So a long time ago (and I mean a long time ago, like pre-release or around release) there were a lot of requests from players to have purchasable skins be more than just recolors. People felt displeased and wanted something more along the lines of League of Legends skins where the character changes more significantly. TRS devs were adamant that one of the balancing factors of the game was that each class had a specific silhouette shape (Assaults were huge and bulky, medics had a V-shape, trappers had a  shape, and supports had a ^ shape) in order to facilitate quicker class-recognition for monster players. In other words, they wanted you to be able to quickly recognize and pick your targets.
Fast-forward and we now have Renegade Abe and Paladin Parnell. The “silhouette” rule has been broken as there is a small non-armored assault and a bulky armored medic. Now, don’t get me wrong. I’m totally fine with this - I never thought the silhouette rule was that important to begin with. League of Legends players, even in competitive play, deal with skins that drastically change a champion’s colors, shapes, and even spell effects, and they deal with all of this just fine.
My point here is that, now that they aren’t adhering to the rule, maybe it’s time we can get skins that have more to them. Goliath that looks more like a Pacific Rim kaiju, a Wraith that looks (even more) like a Xenomorph, a Behemoth that is more flesh than stone, a Kraken skin that is an homage to its Grounder concept art (can you tell I’m a monster player? Insert your creative ideas for hunter skins here )… they could even change the ability effects or colors.
Call these premium skins and slap a price tag on, I don’t care. But I think a door has been opened that definitely ought to be explored.
TL;DR I think (when the time is right and the resources available) that we should get better full-body hunter and monster skins that change more than the coloration.
