Ok, I don't know if you have noticed but Servers in early minecraft (Like minecraft 1.2.5) used to have awesome plugins
Now I would go to those servers and they would be PvP or Jail or Survival and none of those plugins. Or the hunger games isn't as fun. They changed the rules and stuff which made it no fun anymore.
I think there are some good server out there but they are just hard to find through the overwhelming amount of bad servers. Many servers are ran by people who just set up a server the easiest way possible. The better servers are the one's which have experienced owners and know which plugins to use and how to configure them the best. Also servers which write there own plugins are quite awesome because they are unique.
