I'm not interested in reading any more qq. Lets discuss how we're going to adapt and win.
What changes will you be making to your spec/rotations to maximise your contributions in 1.2?
With the Ionic Accelerator procs coming less frequently but more consistently, I think awareness of the lockout timer on IA procs becomes the key to playing Assault well.
For example, a number of Vanguards advocate opening with Ion Pulse over Incendiary Round because it is cheaper. In 1.2 you risk getting a IA proc and locking yourself out IA procs before your original High Impact Bolt is even on CD. So, at the start of fights, I'll be using IR, HIB and then Stock Strike or IP for the proc.
Once you have an IA proc, it might be worth saving SS to use as soon as the IA proc lockout comes off of CD to give you the best chance of proccing immediately. This might not actually be worth the loss of damage you suffer from not spamming SS whenever you can, but at the very least it will make sense to be aware of the IA lockout and hold off on SS if it is coming off of lockout in one or two seconds.
Finally, if HIB is about to come off of CD, it makes sense to avoid abilities that proc a CD reset so you can get a CD reset immediately after using HIB.
Since I presume we are not going to see the IA proc lockout, we are probably going to have to learn to count GCD or use six second rotations after an IA proc to keep track of the lockout.
Regardless, Assault Vanguards seem like they are going to require a lot more skill and attention after 1.2.
Good luck and let me know if I missed something or am just wrong.
