Looking how cataclysm is going it seems that if the npcs arent fighting in the war their poor and homeless so how bout a way to fix some of this and get some rep grinding from it and make it a fun way to gather money to help the economy in the game.
here my idea:
Giving money to poor and you can choose how much to give and it'll give rep and maybe there could be a effect if blizzard wanted to make things cool like if you give enough money to a poor guy and he'll buy supplies to build a house that was burnt down or they can build a flight path or different things cause phasing is gonna take a big part in the game and doing this can make places that are covered in broken houses and knocked down tents to look alot better.
Could even take it further and say sometimes you can pay a guy money and he'll hire mercenary's to go take back his farm,house or other things.
Just saying a idea i thought of while playing the PTR and i thought it could be cool to help the rough economy in the game.
