You get four 587 pieces that are also upgradable from renown quartermasters and takes a solid 20 minutes to farm the crystals for it.
Honor gear goes up to 580 if you upgrade it.
Delves can give gear all the way up to 600+ at this point just gotta get a key, which is easy when the WQ’s that give keys are per character not per account.
Not saying it’s the easiest thing, but those are all very “normal” means.
