The shader thing is cool, but I dislike the idea of using Titan ornaments on hunters or making legendaries look like exotics. Imo a class is a lifestyle choice and should be styled to suit it. Exotics are a real token of what kind of player you specialize as. Are you an invisible fiend or a gunslinger at heart? Let the armor show it. This all ignores the biggest argument against those transmog ideas, which is pvp. As a pvp player, you should be able to look at the incoming opponent and see visually if they're a titan or hunter or warlock. You should also be able to look at their exotic and say, hey that's obviously a guy running blade barrage instead of looking at him and saying hey he's got Gwisin Vest on so he might spectral me but also has Shards on so I'll likely get blade barraged but also has Nighthawk on so he's a nut job who wants me dead six times over with his one golden gun shot. The logistical issues are everywhere. Edit: if you've ever been nighthawked by someone in pvp, it was probably me. I have a flair for the dramatics.
