The only thing i want to see, that not everything is tied to the same GCD.

Why is flash on the same GCD as butchers block. Or shield bash?
I can whack with my sword and cast flash at the same time. And Whacking someone with a sword and the shield without a major delay is also possible.

Apart from that. I have no issues with GCD. That down time when changing classes in field, that could be shortened though
