Yes I highly recommend staying or trying this server. In fact I'm still going to play in the server by the time they re-open. The farming rate is decent enough to for you to able to find the specific materials you needed to make a particular equipment that you need. And as for the EXP rate, it is also alright.
It technically only took m like 1-3 hours for me to get to 65+ near the max level cap as an experienced player. The only issue which I think should be sorted out are the things that I've mentioned, which is the staff handling the server and the people behind it. They just need to be more professional on their issues or concerns instead of ranting it all out to the entire users, making the server's status questionable.
Lastly if you have never heard or tried the game yet, this server IS definitely the one that you should try out. All you needed is a Portskadi or just a encyclopedia in the game and you'll be perfectly fine.
