I agree thieving has gotten very hard ever sense they did this whole guarding thing, I wish they could have a pop up that says "so and so would like to pick up your item, will you allow? YES/NO" that way if a decent RP thief walked up and RP'ed a theft then the other player would be able to continue the RP by letting them get away with the item or RP back saying they noticed and stopped it or whatever. would come in handy in other instances as well.
I'd like to point out that the guild houses come with un-pickable locks, therefore if the guild left it unlocked and the theft was IC, there is no one to blame if they can't catch the thieves at hand. Welcome to the real world. Crime happens. Perhaps everyone should check twice to make sure their houses and guild houses are locked before leaving, I know I would knowing the shady people around hydlaa...
