I used to be a big server owner, of the server Fragslip for 3 and a half years. It got huge for 4 months then the server got a virus, one that could not be fixed. July 5th I am going to be officially launching Razne faction server. It may not sound like much but I have had tons of server experience so everything will be perfect, I am already choosing out plugins and configuring them, making them work with any plugin activator like bukkit or spigot, the server is to be 200 slots and upgraded to 400 slots when that 200 is reached. Were I need the minecraft communities help is, what plugins should be used in this new server. I am putting 400 dollars into it at first so any cost can be covered and if little donations come in the first month or two I can still host it.
Were I am stuck with the server is, what plugins should I have, I can have tons since the server already has 8gb of DDR3 RAM.
Here are some plugins I already have been configuring:
Buycraft
CombatTag
Craftbay
DisguiseCraft
Essentials
Essentials Extra
Factions
Lockette
mcMMO
Promote
Nocheat
rtriggers
simplevotelistener
vault
votifier
whatisit
world edit
world guard

I will probably find more good ones, but I need some ideas for plugins. I can have many since I can get 16 GB of RAM and I have a i7 3.40ghz 4-core proccesor in a private server. Thank you!
