I'm more meaning, items that are specifically given to a char as a reward for their activity. Example: Mauja's staff, Cera's armour, etc. Why have these events at all, if they can just be stolen, thus removing the 'special'-ness of the event, the reward for the activity, etc?
I understand that sometimes these events give out, for example, companions, or magic, which aren't steal-able by nature - couldn't the same be applied for items given out in this fashion?
