Survival /region

I remmber in an old server I used to play in survival ALOT with my friend there was no /claim!
there was /region
what gives you more commands for your region for example:
/flag pvp allowed
which allows pvp in the claim.
also /flag mobs notallowed
which makes mobs not allowed on the claim.
this way you can make alot of more cool pvp arenas, shops, farms and alot more.
I know there is /region but it dosent work
please fix the system or make a new one.
