okay bros im probably gonna get this. What side is the Alliance of wildstar?
Well, Exiles as a whole are Browncoats from Firefly/Serenity.
Their alliance has humans which are the Browncoats, very specifically.
Aurin which are stereotypical tree loving cat/bunny people. Aggressively stereotypical. hyper. giant hippies. Vegetarians. (although a running joke of the vegetables they eat being sentient.)
Mordresh are space zombies/cyborgs. (Made an immortality serum. Serum also worked on all the diseases for their species. Immortal plague.)
Granak are rock people. Very militaristic.
Very disorganized as a whole. the rag tag alliance as noted. but pretty clearly the "good" guys.
Dominion are space Nazi's.
The dominion has a religion that is fairly "good" in theory. but is very clear in practice, you are a Nazi. although, there are a number of missions where you do root out some assholes giving the dominion a bad name. on the other hand, there are also missions where you torture dominion citizens trying to get them to give info on Exile sympathizers.
Cassan have higher and lower classes based on how much of your genome is Eldan.
Mechari, are murderbots built by the Eldan to serve the Dominion.
Draken are klingons.
Chua are captain planet villain hamsters. Destroying the Aurin homeworld. Goblins from WoW more or less.
So, if you mean who is the organized and the "hometeam". Dominion.
If you mean, who is the good guys? Exiles.
