Bioware already said they have huge plans for companions and relationships, but only so much could be added now at launch, Soon same sex relationships and so on will also be added, As of now a few options are in but not explorable at the moment. More will be comming, Just dont rush.
Rushing was the fall of DC Universe online, had awesome content but everyone was end game in a month or two and slowly left the game after doing all the raids, Take ya time, explore other Class stories and so on, see the other companions out there ^.^. DOnt rush the game, Lets enjoy the experience and keep things alive, Lets not get to the point where we are threatening to leave unless bioware gives content now.
>_> Yeah er... didnt mean to hijack the topic with my mini rant ^.^; I just wanna romance Mako
same sex relationships in this game i dont think so... thatll be the day this game dies and we move on lol.
