Boxing Benefits/Difficulties in SWTOR?

Quick Question.

I loved multiboxing wow. Will probably continue multiboxing wow (working on my first 10-man team).

However, my brother (who barely plays games at all) is playing SWTOR - his first MMO & Video game.., which means I'll have to at least single box this game. With Companions in this game being a big deal - I imagine until level 50 I don't need to multibox at all no will we have to group with random players?

Aside from the "love" of multiboxing - is there any clear benefits to multiboxing in this game PVE wise? Crafting? Getting Gear? etc? Not even sure if benefits is the right word... just can't think of a better one lol.

In WoW it seemed like a natural progression after single boxing for years... but for some reason going from 5 to 4 makes me thing grouping will be that much easier... not sure if there were other features that would benefit/hurt from boxing. (For instance, I remember Star Wars Galaxies had space combat, which I don't think was boxable?).

I can't imagine doing Raid Boxing at all atm (I am just now touching the surface of that in WoW - which has a much stronger toolset to do so and the difficulty curve gets higher).

Not sure if I am making sense, but I get the feeling that this is one of the fewer MMO's that single boxing and dual boxing might not be as big of a difference as other mmos, but I really haven't kept up with this game at all. Right now I'm only playing due to cross-country Brotherly Bonding!

I guess secretly, I want to be convinced.

Thanks for any advice and thoughts - this community is always very insightful!

There are quest that are Heroic. If you want to do these solo boxing will allow that. Otherwise you have to hope for some help by grouping with random people. I may try to box 2 characters just so I can complete the heroic quest.
