I have to say I agree. Servers nowadays simply aren't good anymore, both in build quality and gameplay. Even simple freebuilds were more fun a couple years ago than what we currently have now.
I remember playing Blockland before physics or events came around and having so much fun, I didn't know what server to join because most of them were actually good back then. Now, I don't know what server to join because none of them look like they would be remotely fun, and if I decide to take the time to test that theory, it usually comes out to be true.
I'm sure the fact that I have gotten older and have seen quite a bit of what Blockland has to offer doesn't help the situation, but no one can deny how bad most servers are now.
