I'm a non-German player that made a mistake of using a German server and I don't want to spend extra money on the character transfers so, for now, I'm forced to stay there.
I've got a Jedi Sentinel, lvl 55 with 156/164 rating gear and I'm ready to fight!
Sorry, but: You brought a Jedi Sentinel to level 55 without noticing, that you're on a German Server? Was the German chat not a bit of a clou?
For Operations you should travel to the fleet and look for groups there, you can read the lfgs all over the common chat there.
