So fyi, this is just an idea, so don't get your hopes up or down when you read this. So in destiny, every guardian (with some exceptions) is so sure that the Traveller is good, calling the cosmic magic it gives us "light" and saying it "sacrificed" itself to "save us" from the cosmic witchcraft black magic pyramids called the "darkness". And with it's final breath gave us ghosts to find the guardians, blah blah blah.... You guys know the story. About the darkness being "another subclass" theory... well what if the darkness involves guardians of its own forged in "darkness" with its very own versions of void, arc, and solar subclasses (I know this isn't the first time this has been said). Well I say if it does, then a cool thing to add into the game is the CHOICE to be FORGED in LIGHT or DARKNESS! And that choice impacts the campaign, places you can go, how you play other people, and yadda yadda yadda... You guys get the point. May be a stretch, and probably is. But still it'd be cool though. For instance, PvE could be PVE AND PVP. Say you've gone exploring during patrol and stuff, then BAM you get a notification that a DARK GUARDIAN has entered you're area also exploring and doin stuff. Well, you can't just leave him/her alone and he/she can't leave you alone cuz you know, the eternal battle between light and dark and what not. So you gotta go fight them. Now, I've realized this may get boring after a while and people may start complaining so that PvPvE may not be a good idea. But whatever. I think this idea of choices impacting the dynamic of the game would be cool! Oh, and this other thing that'd be cool... none consumable shaders! 4 customizable emote slots! That stuff is definitely cool too.
