There is nothing wrong with the attack chains you have.
I'm saying without the global recharges which just aren't realistic for the average character. The benefit might be substantially less. It's fun playing with max build type numbers vs pylons but how applicable is it for normal average folks?
33.3%, 38.6%, 62.7% recharges are much different than 356.5%, 398.7%, or 500% (edit: I left out Hasten on top of the 33.3%, 38.6%, 62.7% that's my bad)
