Guild Wars 2

I think the guild emblem should be placed on each armor we get not only on the specific guild armors. Think of it the decals placed on the car in any car racing / tuning games.
The emblems can be also put on weapons by a simple tuning system that will add the specific place on the weapon for putting the emblem: especially for staffs, specters, focuses, bows and torches

While this is a great idea, it would take an incredible amount of work to implement. Consider for instance the number of different armor types in the game, and that not all of them have an easy to place location for a guild emblem.

they could use a system like this
