So, I've been playing this game since launch, coming back sporadically for a few months every year, and I think the one thing that's most lacking is PLAYER SPECIES OPTIONS.
The additions of Cathar, Togruta, and Nautolan, while fantastic, don't feel like enough for a game that's been running for almost a decade, won't be adding any new classes, and is supposed to take place in an expansive universe filled with a colorful cast of aliens and otherworldly creatures. I thought they might capitalize on this when KOTFE came out, especially in light of changing the companion system. The purpose of many of the expansion's changes, as I understand them, was to maximize player choice in both playstyle and story. Unfortunately, new player species wasn't really included in that ideology.
Arkanian, Bith, Bothan, Chagrian, Devaronian, Duros, Kel Dor, Mon Calamari, Nikto, Rodians, Selkath, Sullustans, Trandoshans, Weequay and more! Even more difficult races like Ithorians and Wookiees with little to no armor choices would be welcome! Of course the process isn't as simple as all that, but much more effort should be put into making this a reality. Even something like, and I can't believe I'm saying this, cosmetic alien armor sets in the CM would be great. There's a whole galaxy of recognizable alien species in Star Wars, many of which already exist in the game, that are just waiting to become playable! Not to mention that there is undoubtedly a great deal of praise, and reward, waiting for the studio and developers if they take action on this!
