I agree, there should be more roleplay, as I LOVE to roleplay.
For more races, some ideas are:
Elves, who can jump higher, run faster, can see better, have a very very very very light aimbot for bows, etc..
Dwarfs, who have 25% quicker mining, a strength boost, etc...
Wizards, who can make magic, do spells, etc...
Mages, (or whatever you want to call them) who can make different potions, heal vampire-indused sicknesses, etc...
Werewolfs, who get strength boosts ONLY at night, can run faster at night, etc...
There can be downsides added to all of them (like vampires burn during the day) but, you guys can sugest some.
I've seen more posts about this, but I strongly think it should be added:
Add to the 'Factions' plug-in, like making it so that you can make different ranks in your faction, and add perms to those ranks.
(example: Co-Leader, who has all the same perms as Leader)
The 'Events Portal' should lead to a room, which has MANY portals, leading to different events, so there can be many server events at a time, and a way to advertise your own events in the Events-Room, And get a server mod/admin to make a portal for it.
some sugestions could be:
A religion that worships the elder gods of massivecraft,
A religion for vampires,
A religion of creeper worshipers, like the ones that 'Daendroc' was formerly home to.
Have a Massive day!
