You can solo most fates as dps with your choco. The boss fates are sometimes too much handle but with one other they are doable as well. You can get the low 60s fates in the fringes. Usually 3 or so up.

You can do as others suggest as well and use PF or lvl crafting/gathering in between. That would ofc make it take longer to hit 70 but you get other things done in the process
