for 5 20 sec bursts with a cooldown timer the fighter does more dps, but what is your point. How really practical is fighter haste boost? I use my 5 boosts on both part 4 and 5 of the shroud of course, but the fight lasts longer then that and it takes a sec for someone to activate a haste boost which is a loss sec of dps by the way as well if you have to do it in mid fight.
