Best Premium plugins for Faction Servers

Any plugin suggestions for faction servers? Share your favorites!

I'd say get ShopGUIplus and EpicHoppers would be cool

Custom enchants are pretty cool for Factions and if you want to move to RPG styled faction then there's a whole plug in that will completely modify your server to be like adventurous and MMO themed with powers and all those cool stuff. McMMO is great too

I recommend CMI.
It's really essential plugin to every server.
It contains economy, shop, portals, holograms, scheduler etc.

Custom enchants, mob arena, silk spawners, safezone/warzone warp...
