I'm a lv 70 druid so I have Stormcrow form. I found that I can very effectively collect tons of skins without ever having to make a kill. I'll glide through the skies while chatting with friends and keep an eye out for dead animals. I just swoop down, skin them off the ground, then fly away to the next one. If I find a player who seems to be killing a lot of enemies, I will follow them and just skin what they leave behind. That's what vultures are supposed to do isn't it?
