Hello Strawberrii!

1. Stay on Balmung! This server is absolutely amazing and has one of the BEST communities in the game! If you need a friend or someone to chat with, look me up!
2. Not too difficult at all, especially now that Lore Tomestones have been unlocked and ilvl 235/240 is easily reachable. The mechanics are interesting in First, Second and Final Coil. My time raiding with my static in Coil has been one of my best in game memories.
3. At level 60, a lot of jobs become a little complicated. The additional abilities definitely make the jobs stronger, but complicate your rotation. Yoshi P has acknowledged this in recent interviews. My recommendation? Pick a job you absolutely enjoy and focus on it for now.
4. So FFXIV now has Instagram-esque filters/camera in game. Groups can sync their pose, pause it mid pose, then take screenshots with filters to make it more interesting.

I hope that answered your question! Feel free to look me up in game if you have any more.
