Personally I would blame Demonkunga for releasing the edits, but nothing I can do, not that I care, I'll level my warlock...
Demonkunga got nothing from releasing the edits except +rep, hate and noobs who hack in BGs.
He shouldn't have released his edits at all, it was more than clear that leechers would use them to hack, and he knew that he had it coming.
I wouldn't take it as "someone was going to do it, sooner or later, it was inevitable".
Why would I kill myself when I know that we all die at the end?
But what is done is done, there's no point in flaming him, it's just my honest opinion. No offense, no harm done.
Just severe disappointment.
And no, model edit fix won't help you after 2.3 since WoW won't read custom patches. As for editing the MPQs directly, yes it's possible, but not worth it, Warden might check for changes in the MPQs.
EDIT: wtf I'm wrong.
Once again, no offense, Demonkunga. Just my own point of view.
