Hit 1580, what should i do?

Good evening, i am looking for suggestion and help in order to proceed in the game in the most fun and painless way.

JS player, have a 4 char roster, 3 dps + 1 supp, i got DE 1580 (through path of the soul eater), Slayer 1563, SF 1550, artist 1540. Roster level 115, have all skill point (besides ignea, only got 2 igneas), most of the leg runes. Horizontal wise i should be good. All char level 7 gems, DE has the lvls 8 from event.

At this point i am thinking of solidifying my roster and farming cards, i am not too far from LoS 18 if i use selectors (KLC looks like a mirage instead). I can consistently get in clears for all content of ilvl 1540 so i have some weekly gold guaranteed. Have also done a few brels hard but the time it takes to get into a group is not really worth the hassle.

Since i got 1 char to 1580 i am going to join learning groups on discord to learn akkan. Suppose that i learn akkan, where should i go from there? I'd like to do akkan regularly at least with 1 char. Where should i spend what i earn?
I'd like suggestions because the 1580+ endgame looks even less welcoming than the previous tier of endgame content (from a gatekeeping/requirement perspective).

PS: I've tried to find static/join guilds/join discord. I've played with some people but tbh seems kinda hard to find a mix of people you find yourself comfortable with + they play with a similar schedule + they stick to the game. I am also not particularly extroverted so that's a thing too.

Rant: Guilds sucks. Most of em recruit just to have more people for activities/bloodstone farming. There is no real interest in adding more players to the raids once the core group (if there is one) is formed. So in the end joining a guild who is recruiting is pointless.

The best way to play this game is to join a static but that's easier said than done, especially since there are not a lot of new/returning players to form a same experience static with.
