Well I've heard it many times, swtor is too simmilar to wow. However you feel on the topic, I still thinks swtor is a better game. That being said, some game changes I'd like to see:
1: Make another facion other than republic and empire, you all already have a section for nurtral characters in the database, why not expand on that? For example 4 classes a ranged class, non-force using melee class, and maybe 2 new non- sith or jedi force users (like force adept and dathomir witch or something)
2: More species choices. Personally i was upset at the few species to choose from. Some species I have seen much support for from fans are Wookiee, Bothan, Rodian, Echanii, Devaronian, Jawa, Kel-Dor, and Togruta. (Personally Wookiee alone would make my year) With all the species in the Star Wars universe, there are literaly hundereds that could be chosen from.
3: Color customization of armor even if you had to pay to dye the armor i think it would help with creating more individualality amongst players
4: Visual depiction of offhands (focus, generator, sheild)
5: Guild ships: a place to meet other than fleet
I hope the developers will look into some of these suggestions and institute some in the near future
