You should make an awesome RPG server that would include:
1. Awesome spells, abilities, and items for each class you have.
2.Awesome terrain.
3.Cool cities/towns.
4.Spell books that give you new spells.
5.Lots of amazing looking dungeons with puzzles, loot, traps, and mobs.
6.Custom mobs, drops, and power ups.
7.NPCs you give you quests that you can do.
8.Other dimensions maybe?
9.Shops and clans.
10. Other plugins I guess?
That would be an awesome server IMO
