I can't really say what BioWare could give them that's better, but I mean, there's likely plenty of stuff you can easily give them instead. I mean, they already have all the cool physical stuff.
But I suppose, what you could do, is give them something more distinct, perhaps something that resembles Darth Vader, or whatnot? (and dont go on about lore with the armours, they've already added TFA snowtroopers), maybe even allow them access to a different variant of Trooper armour, like an Officer set? I dunno, you tell me.
All I ask for, is the ability to be able to happily RP with the AUTHENTIC Trooper armour, Makeb is just poverty. Whether I get it through direct CM or if I can digitally upgrade to the CE on SWTOR.com - it'd be nice to finally wear it.
