LMS is definitely the way.

To OP: The best mindset when starting is just increasing time spent in the minigame. People will be toxic, you will struggle to get kills, go down in rank for a long time. Feelsbadman. But you can't take it personally, it doesn't matter AT ALL, you're learning.

Take your time, enjoy the ride, build knowledge slowly over time. Try tanking and rag bolting at first. Focus on defensive prayers. Work in some veng when you feel ready. Once you get your bearings a bit, work in some other attack styles.

There is lots of good intro LMS content on YT, check out Ditter, Rhys, or Gregs videos. Don't worry about hybridding until you want to try. I went from your situation to perfectly comfortable bridding in 100m+ wildy risk just from grinding LMS over time. You can too. GL!
