Its different then a gcd because it goes off even on a 5sec cast time spell. Where as with a gcd, after a 5sec cast time spell you would immediately be able to cast again. e.g A .5 sec cast time goes up to 1 and a 5 sec cast time goes up to 5.5 If you read the end of my post, i say that i think a gcd system is the best for wildstar. I was just showing an example of a game that has no gcd, and avoids problems people were talking about. Its just not possible to do no gcd with only 10 skills and have it feel good.
