tldr for those who cba to watch

Zepla mentions the following issues in no particular order

1. Netcode
2. Glamour dresser
3. Gearing taking forever
4. Menus/inventory system
5. Difficulty of installing/setting up your account
6. Level sync removing actions

while she's not wrong about these issues, she's completely missed the most important ones: jobs being crap and unrewarding to play (especially healers) and lack of repeatable content and midcore content
A game literally cant function without a good gameplay loop and the poor content and poorer jobs are whats causing this game's decline
