...and? Here's an idea: Apply for a job at Blizzard. Sit in your cubicle eight hours a day, five days a week. Make sure you have a cover sheet on each one of your TPS reports. Go the extra mile and get noticed by your boss. Work your way up the middle management food chain. Get a job in the department which handles Blizzard's resources. And then make the ever-crucial decision to implement old models because I'm sure there are literally dozens of people demanding it!
You can bet old models will be disabled eventually.
It makes no sense to keep updating old models whenever something is added to the game. This includes new head gear, customization options, skins (even for NPC-only skins!), new animations and, in demon hunters, animations/horns/tatoos and so on. Updating old models is doubling the work for minimal benefit.
Sorry that you don't like new models, but the best you can hope now is for Blizzard to include skins/faces that you like in the future.
cause old models are shit
Avatar and Sig by Serryn. Amazing TY
They defo can but that's unnecessary hustle. As someone mentioned they had upgraded skeletons, so now we have 3D-ish armour, better animations, etc. So essentially they'd have to overhaul old models once again to give them new skeletons, hm.... but... that sounds familiar, damn...
IIRC, you're studying something SE-related. In software development backwards compatibility is often maintained until it becomes a hindrance, otherwise it is removed or isn't even implemented in the first place. That's the case here, they kept both old textures and old models w/ skeletons intact until it's reasonable, but then they ditched old skeletons.
However, I do agree that many of new models need some love, for instance, fem belves have serious clipping issues T_T
If they allow players to use old models then every future gear item will have to be designed with that in mind. Thats extra work for a very very small percentage of the playbase that cares about this. It might even limit their gear design if future ideas simply are impossible for the old models.
