ExKage, I actually went through something similar to this very recently. Perhaps my solution will work or you - after I left the group that my friends were a part of, I set up a new independent LS and invited them all to it. Many of them were all still part of another LS, but as it turns out, my new one is pretty active too and I stay in touch with all the people I like to game with quite easily.
It's important to remember that this is a game, and games are meant to be fun. If you're not having fun, then it's a chore - and why would you pay to perform chore? Though the people you're concerned about are your friends, everyone has different tastes. You sound like you want to explore end game content more, while some of your friends prefer to focus on slice of life RP. That's fine, and as friends, rather than remain beholden to one another and bring each other down, you should understand that your game styles lies in different directions, and that's alright.
Another tip I can offer is to set up a group skype chat for your people. This is something I did parallel to my new LS, so even if the LS itself falls out of favor as people begin to focus on other LSs, we're still a crowd of friends in the skype chat.
tl;dr: People aren't made of stone. Do what you have to do, and people will flex to remain friends.
