I play as musketeer, I simply don't enjoy the other classes eventhough I'm trying to give them a chance. My pravateer gets reduced risk, which really makes no sense as when I'm playing with my companions I'm still the one that gets rushed and not them. Loud and reduced threat must only work when playing with other people and I'd like to be corrected by the game's admin if I am wrong upon this.
Come to think of it, I've noticed that Privateers are the only class other than Buccaneers that can train to wear Heavy armor. And the more fire I can draw away from my Muskateer & Witchdoctor companions, the less time I spend healing them instead of attacking myself.
