It's hard to tell when people are joking on the internet, especially when it comes to discussions on game development. It's hard to tell if someone is joking or they really think games are easy to make a developers are just a bunch of lazy idiots. For example,
this enlightened fellow believes you make minipets by just shrinking regular models with "a couple sliders." It's kind of interesting timing because there's
a nice little article floating around today about just such a thing.
Anyways, I think it should be sufficient to say that if it were an easy fix, someone would have fixed it by now. That they haven't means it's a much more involved process like the one they outlined. I just don't see a company like ArenaNet, that has delivered an MMO with almost zero down time (in contrast to other games with weekly 5-hour maintenance) and tech like Megaservers, guesting, etc. not being able to fix this if it were really easy.
