They probably havent played enough to unlock those. OP..did you use a boost? If you did, I strongly suggest going back to core and playinv through the personal story and core maps for a bit. You can buy gear on the Trading Post. I'd suggest level 80 rare(yellow rarity) or exotics(orange rarity) if you can afford it, If you do 3 dailys a day, you'll get 2g a day and within a few days be able to buy a full set of exotics off the TP. You could also check your bank > collections ...sell some stuff on the TP to make enough. Mystic coins are worth a good bit to sell. Here's a theif build you can tryhttps://metabattle.com/wiki/Build:Thief_-_Dagger/x_Deadly_Arts(there are also other builds on this site.)Chances are you're not using your skills right/dodging or you're not in level appropriate gear. Avoid toughness in your armor, it doesn't help. vitailty can bht. Most people use bezerker gear. (power, precision, ferocity) in openworld but it can feel a bit squishy if you don't know how to dodge. yes i did boost, im currently just using the gear i got from the boost, the Valkyrie set, im gonna try the build in the link you gave me and go back to my personal story. thank you
