Yeah there is going to be a one second delay. It's going to feel awful because the skill speed drift. I don't use big boy openers all that much due to my different playstyle of build long burst big. But I can see your problem. The limitation is rather taxing and unnecessary IMO. Removing the 6 second delay would be better I think.
Most of the vocal minority on the forums is awful. If you want raw opener/rotation discussion you have to stick to Balance or figure it all out yourself.
I hate the balance myself. Don't like it. The data and info is good though.
But I'm a Reaper player so of course I can see the issue you are having. A lot of the other people have too much salt on Reaper for being the DPS king to give helpful feedback.
