Remove rng from it and we'll be fine, you can even make it slightly more pricy (although personally I'd prefer not :)), like 500 gems for a reskin, 800 for total remodel (gliders are completly remodelled and for 700 we get packs - glider+backpiece for crying out loud), but 400 to get some random thing and 2000!!! for remodel? No. Don't make GW2 that kind of game.
