I know there are various posts about this type of thing but i don't think any of them quite hit it. But i think that Bioware is seriously missing a market here. I know it takes a lot to do, and even more to do tastefully but i think it'd be worth their time. I think there are three basic types that would make it too, just by fan base. Ranged wookie companion. I know we have Bowdar, but really, how many people would love to have a wookie with a bowcaster at their side. A female (possibly chiss) comp, probably ranged. Just something different to throw in the mix with all the rest of your crew. And a male force user companion. That's right, because of all the companions who can use lightsabers, only Lord Scourge is a dude. And making a saber wielding comp for everyone would just be fun. I know i have a couple of alts who'd love a bodyguard like that.
My two cents at least.
