So you link a guide and then disagree with one of the Cons stated in the guide:
"Damage relies on constant monitoring of skill CDs, Rage, incoming Rage and Fury"
I.e. that the playstyle is pretty complicated. Whether or not it's overly complicated, of course is a matter of opinion. Note, however, that there are other classes to play, and the playstyle of these classes can inform our opinion about what a complex playstyle is, and how it functions.
BTW, I solo two man heroics on my Marauder too, my BH just solos them easier. I also like the BH's resource system better, as it is not something cut and pasted from that "other" MMO. Finally, I know why the BH solos easier; it's because of crowd control.
BTW, I'm not trying to nitpick your post, I am completely comfortable that other people play the class better. I am not sure, though, if I am comfortable with having to have some sort of exceptional talent in order to even compete with other classes that can be very effective in the hands of average players. Honestly, my BH feels heroic, my Jedi doesn't.
