As far as I understand there are some procs but not too many and they have a high probability. For example lets say in average it procs all 10s, after the proc I have around 10s to push the button. So my rotation will just push the button after 18s. Most of the time the buff should have procced by then. I will never achieve perfect damage output but I guess 90% is possible. I think thats good enough. Also other classes have procs and bounty hunter + imperial agent are probably very hard to box perfectly due to overheating / energy problems. I guess with these classes the boxable rotation will also only make around 80-90% of the perfect DPS. Maybe sith warrior would be easier but its a melee class, I dont like that
