Obviously it's a tighter window with no skill speed at all, but you don't need insane levels of skill speed or anything either, just a matter of timing.
You gotta take the activation time of your zerk and IR into your account. Roughly 0.86s per ability, so ~1.7s for both zerk and IR. Even with 2.4s GCD the time window would be pretty tight.
In 3.x if you had a GCD of 2.42s it was "perfect" for "3 FC+Fracture finisher", yet I heard many WARs complain that they weren't able to fit in Fracture due to server lag or difficulty on console control.
Just a lil skip/clipping can cause your rotation to fail. 7 FCs is risky, leaves you with 5 BG points and is overall weaker than 6FC+Upheaval+2 Onslaughts (+1 possible HSwing).
