Love all the companions that we have acquired throughout all the expansions. Some I have a deep connection with, others are strong allies who I love to have fight by my side. Though we have had some new allies added to the roster (Gamorrean Guard, Shae Vizla, Darth Hexid, etc.) I personally hope to meet a few more with this upcoming expansion. Even going so far as to introduce other races in the galaxy.
Imagine a Quarren ally, or a Falleen. Maybe even Givin, Dug or a Porg! (Okay, Porg is a joke ) Or how about races that we are familiar with? I was surprised we still have not received a Rodian or Kel Dor ally. I know, there are so many possibilities and we couldn't possibly go through them all, let alone get a companion from each race. Just throwing out ideas.
One nitpick I do have though is that we are seeing little to no options for customizing some of the newer companions. Examples are (Arcann, Nico Okarr, Paxton Rall). Maybe they are in the works to getting fixed to allow freedom of putting on armor pieces like they did with Lana, Koth, Shae and so on but even if we couldn't get that option, at least lets get some new skins in some of the cartel market like we did in the old days.
I don't know, am I the only one who cares? I know it's not a BIG deal but I certainly like to customize and create in my own way and I know there are others out there.
