This post contains significant spoilers for the Bounty Hunter story in Star Wars: The Old Republic.
With the renewed 12x bonus, I finished up the Bounty Hunter story. I played as a somewhat Dark Side female Powertech DPS. I was trying for the consummate professional at first, but slipped over to pure brute Dark Side for a few planets.
If I had been in charge of SWTOR development (and had unlimited time and money), I would have scrapped the Bounty Hunter story and sent it back for a complete rewrite. It's not that the story is bad, precisely. It's serviceable, reasonably decent, and does cover the basics of bounty hunting pretty well. You're a hunter, here's your target, go get them.
The story is just not good enough, though. There is no over-arching theme or purpose. In each chapter, you're working for a different patron, who sends you after different, unrelated targets.
A lot of the problem also comes from the fact that a hunt is pretty much how every quest in every MMO works. Someone points out a target, you go and kill the target and they give you a reward. However, every other story has some extra dimension to the request. The bounty hunter is missing that extra dimension. So it feels like every other story in every other MMO, just "less".
The other class stories all had flaws. But those flaws were fixable. The underlying structure for those stories was sound. In my view, there's no real way to improve the Bounty Hunter story outside of a complete rewrite.
I'm not really sure what a better Bounty Hunter story would have been. Perhaps something that delved more deeply into the Mandalorians, maybe with you ultimately leading a new Mandalorian clan.
There are a lot of good elements in the current BH story. The crew and their interactions in particular are very good. One interesting item is that Mako and Torian are the romances, but there also seems to be an option to set them up with each other.
Many of the individual planet class missions are good, with interesting targets. The final mission is very good as well. But the individual planet class missions feel unrelated to each other. The only relationship is that your patron wants these targets.
For smaller flaws, the main antagonist is not that great. You don't interact a lot, he's just an image on the holo who occasionally sends incompetent Jedi after you.
The companion Gault is also a flaw. Not so much in his character, as he's a great character. But he's a target who convinces you to let him fake his death and join your crew. Yet one of the bounty hunter "fantasies" is to be the ultimate hunter, the one who always gets her target. The game forces you to violate this ideal, forces you to avoid killing or capturing one of your targets. No matter how awesome you are in the rest of the story, Gault will always be a blemish on your record, even if no one else knows about it.
Then we come to Skadge. Skadge is probably the most hated companion in the game. He's basically scum of the earth with no redeeming values. The bounty hunter has no reason to take him along. It's like Bioware wanted him to be the equivalent of Khem Val. But the Inquisitor needs muscle, and an ancient Sith monster that eats Force users is an awesome companion. But Skadge is just dumb, psychopathic muscle. The Bounty Hunter is already the muscle in the group, and doesn't really need an insolent extra.
Skadge really needs something in his character to make him attractive to the bounty hunter. Perhaps something like playing up the dumb, evil part of things, but have Skadge look upon the Bounty Hunter as an elder brother or sister.
In any case, that's what I thought of the Bounty Hunter story. It's certainly serviceable, and it does fulfill the Boba Fett fantasy at a basic level. Individual planets are pretty good. But as a whole it pales in comparison to all the other class stories in the game.
