I personally don't need 2.5 seconds to decide my next move but I don't think 2.5 is that bad. I think 2.0s would be much better but it's really not a huge deal. Although if we went to full on slow paced combat I'd probably play a different game. I enjoy having some action and keeping my momentum going, I loved slow paced MMOs when I was younger but that's also all we had really. I'd never wish for the days of Click on Target A , go make food and check screen every now and then to press one button to come back. Combat like that doesn't keep me invested. It was nicer for talking to friends but this way is more fun for me personally. Even with that said I still think the current GCD is good enough for me.
