It is actually a lot of fun if you're lower leveled or undergeared. You need to be a lot more careful with what you plan and how you sneakily sneak around.
It also helps if you have some good friends, and a good guild is much more meaningful than just a chat channel. It's actually a very social type of gameplay.
That said, it's fine if you don't understand it. You don't have to play those games or join those servers.
