I've been playing since early access. Still only level 41, I believe.
I really appreciated the advice I got several weeks back, when I said I felt I was going too slow and was missing out. A few of you pointed out that I should not concern myself with what other people are doing, and should just play at my own pace. No reason to play a game unless you're having a great time, right? So, after that I played from ~38 to ~41, had a lot of fun, but then ME3 came out and my interest was diverted.
Unlike a lot(!) of people, I thoroughly enjoyed Mass Effect 3. Thought it was an absolute blast. And so I might replay through the trilogy, and I'm also grabbing Kid Icarus this weekend.
My account expired on the 20th. But I have another 60 Day Time Card sitting right here on my desk. I think I'm gonna wait for the 1.2 patch, and then use up that 60 Days. Should mean there are more people on the planets doing Legacy stuff, and hopefully my Jedi Knight Sent will see a small/medium boost in power. And I'll probably ding 50 and play a bit of endgame stuff.

TL;DR: I appreciate those who told me to not concern myself with other peoples' progress - that there will always be LOTS of people with significantly better gear and exp than you. But there will also always be new players coming in trying it for the first time. Just enjoy the game at your own pace. And I'm just passing that advice along.
