perrond, my understanding is that although CoH was still making a fair amount of profit, NCSoft had new games (Blade and Soul, among them) that they wanted to put all of their resources into. It was geared toward their fan base in Korea. This is their priority, not US-based gaming communities.
So here we are after all this time, with our home back thanks to 6 years of hard work in secret by Leo and helpers. Where is the big failure, Blade and Soul? It's where it should have been from the start...non-existent. I think that 15 years of non-swerving devotion from the CoH community should be a great lesson in loyalty to everyone.
