I got mine to 330+ very fast just by playing what I wanted, when I wanted. Now I have 1x 335 and 2x334 (had all 334 from about 10 days ago) and am just missing 2x 335 ghosts. I could have gotten those easily if I'd done the raid on all characters all weeks post update then ground CoE, but that wasn't what I wanted to spend my limited playtime doing. Instead I went flawless 3 times this weekend, which is a much bigger deal for me (thanks to all those that helped me on all my runs, successful and unsuccessful, they were all a lot of fun!).
