Have you done ultimates? They're not hard to PF. Just start with UWU and prog naturally. Worst case scenario you have to join fresh garuda prog groups for a long time. Best case scenario you prog well and can move up to the next levels at a good pace. Once you learn what it's like to prog uwu, you can do the same for ucob or tea.

You don't have to know anyone or make commitments. Just hop into a group at your current level and do your best. Some groups fall apart after a few pulls, some reach the 120 minute time limit and keep going after zoning back in.

You can do it. You don't have to worry about succeeding or knowing what to do for the whole fight, because it's going to be a long road for anyone and we all start at the first prog level. You will develop the necessary skills and knowledge required as long as you continue to grind away at it.

Then there is the rest of the game to engage with still while you continue to work toward your totem. For me it's been a very rewarding journey and I've become a way better player as I progress through the stages of the encounter. I am excited to see what it will feel like to clear, I am excited about what I am learning, and I am looking forward to doing the other ultimates.
