There should be a way to turn off pvp.

[DwarfTank]

any way to switch pvp on and off will be misused by players who first kill and then go switch it off.

I see only one way to do this.
u start a char as non pvp. like now until lvl 3.
you stay untargetable until u dwitch on pvp yourself BUT THIS IS A ONE TIME DECISSION. you can never switch it off again .
alsi if u join a clan you automatically switch pvp on perminantly.

This would be fine.
