I have been playing this game with 400+ ms for 8 years, the delay is barely noticeable for this game. However due to the the instability of the game related to drivers/windows/new pcgears/ISP the difference in experience varies from players to players.
Make sure to check out the Guides & Tutorials and the Patch Notes that differs this server from the official one. Enjoy your game. The game is full of cute costumes. I do suggest you begin by interacting with recruiting PvE Guilds right now to help you progress and give you game knowledge. You can always leave a message on VGN here if you are interested in depth of game knowledge.
Welcome, Good luck & Have fun.
