Sparks gear is a step to get going but to get into most groups you will need a little better gear. I would say try to get in skirmish runs with people to get skirmish gear (you could be book person in Alluvion Skirmish to start getting you pieces), and upgrade your AF/Emp/Relic gear. Also depending on jobs you might want to get some delve gear/weapons as well which some are still good for people coming back like the Delve Shark GK if you play sam, etc, and there is still some rings, neck pieces, etc that are still not bad to use for some jobs. You will probably need some help to get delve wins and gear but most places still have shout runs that occur, or if you have a group that does delve try to get in on it. You might also want to think about leveling something besides dark because you will find that dark is not used for most content nowadays unfortunately. Support jobs are wanted a lot like brd, geo, sometimes cor, whm, sch, or DD jobs like sam, pld, Rune, blue, etc. Once you get gear sorted you can maybe do some Incursion for a decent Capacity Points (job points) capes (Mecistopins Mantle with capactiy points augment on it), and JSE (job specific equipment = JSE) cape though you can get JSE capes augmented from a npc without doing incursion with refractive crystals but still need incursion for Capacity Points capes.
