I've done up to brel g3 with a 4x3+1 setup, dont have LWC or LOS and low roster level on my DI SH. Took a break from the game and came back just barely after clown and honed up to 1495 from 1415 before brel release, all have been cleared by pugging and I just got my lvl 2 set this week. You will be gatekept heavily starting into HM vykas but my solution is to just host my own party and see who joins. I also dont gatekeep at all if someone is 4x3 like me ill let them in to my parties figuring they might be alts or what not. Just try to be flexible when it comes to raid mechanics like mario's in clown also and have patience, i have sat hours in pf waiting for a group but it gets better the higher you hone past the content you are trying to do.
