So I'm going to hit level 50 for the first time soon. I'll keep going to 55 after that, but from what I understand, getting gear, etc changes a lot once you hit 50. Up until now, basically the only commendations I've been dealing with are Planetary and Warzone. However, it seems like there's a lot more to level 50+ content than that.
Anyway, can anyone explain to me how things work at level 50+, or point me to a guide?
Also, this is my first serious mmo, and I've never raided before. What is involved with getting into Operations? How long do they take? Can I use the group finder for them like Flashpoints, or do I need to be in a guild to do them?
Thanks!
