My main server is Wound in the Force and I am on the Republic side. I'm not 50, but I have a lvl 40, a 37, and a couple teens. I rarely ever run into Imperials. I ran into some a few times on Nar Shaddaa, which was my first experience, then a couple on Tattoine, and I think I ran into one, maaaybe two on Alderaan. I didn't run into a single one on Balmorra.
I put it in my head that maybe everyone is 50 and once I get to 50, I will start having open world fights, but then I remembered some of the other games I've come from where a big part of the fun is running into people while out doing missions and leveling and fighting there.
I am enjoying the playstayle of the game and the story, but wondering where everyone is? Is it my server, or are other people experiencing this?
I created an Imperial on Rakata Mind Prison to see if it's any different, but I'm only in my teens so far.
