I think if I would tell you now that you slowly overdo it, I wouldn't be the only one who thinks so.
The server definitely has potential, but you should not overdo it. 5-6 new monsters go still, but not directly a force of new monsters. You should not really change too much.
But otherwise I find it really good. You want to provide players with more new stuff, but there are other ways to do it. I hope you take this to heart. Because not everyone wants too much altering. New armor, etc. are good, but you should not really exaggerate.
I wish you much happiness and success with the server.
Yours sincerely
