There is no PvP game that allows you to fire multiple skills at once. Probably not that many PvE games either. Not trying to be a bad guy here but I think everyone's just been spoiled with the way the setup's been. When gcd is added, it'll just be a small adjustment to your play style and you'll move on. You guys haven't even seen or tried a sample of it yet and are already speculating that it will destroy PvE and increase run times by 3 to 4 times the length. It's not going to change things that much.
