If you think you've done enough farming and RNGesus is flat out cheating you, you can always visit the shroud depot. I think they have all the armours at legendary so you could grab the pieces you need at your current biome level without cheating some high level gear. Doesn't really work for weapons unfortunately as they only have the lvl 45/50 end-game weapons. You'd have to go to the Armoury for weapons.
