On a more serious note, I too loved the fire cat model and the other day I decided to level my druid a little bit and noticed that I still had the fire model effect even after changing weapons. I suppose that’s what Senel was talking about in his post.
Anyway, this is far from a perfect solution and might even not even be intended and eventually get fixed, I’ll ask devs about this though, maybe there’s a way to add it along with transmogrification, but I’m guessing this might be simply a design decision, fire cats are cool but they’re also er… extravagant and maybe a bit too flashy, I don’t know if seeing every druid as a fire cat would be interesting or just annoying.
On that note: Could you also talk them into giving us the fire scorpion as an alternate bear form ;)? That would be awesome!
