Some of you are forgetting that the noob stage is a critical and delicate stage.
If a noob is bullied they leave... forever, but an older player won't quit over a minor drawback.
The OP has a good idea. Stealing should be different to raiding.
Thieves don't steal in front of their victims faces, they use stealth and timing if an owner catches them onsight they should leave.
However when you raid you can do whatever you like, such as killing and destroying objects. There really needs to be a distinction between those two offences.
Someone had a great idea a while back;
If you are going to steal you can climb over a palisade with a rope, but obviously you cant climb walls with heavy armour or swords.
But when you raid you can smash right through the wall and do whatever without fear of being kicked.
This combined with the OP's idea and this guys
idea be great and solve many problems.
