Pretty much. Just gotta get to 975 and things start getting much easier, especially with regard to the enemies in the seraph tower event. The bunker clearing can be done solo as well, but the teleporting captains every few seconds is dumb as hell. Can't WAIT for my disruptor sword mod from the artifact... The legendary lost sector is... 1000 power, but, can be done with a fireteam (if you can find one)
