There is now only one skin for each type of armor and weapon. The only thing that differentiate one guild from another is only the emblem. I wish in future expansions, when the guild feature will be developed properly, to see more type of armors and weapons. Lets say there are some guild categories that can be chosen – traveler, conqueror, technocrat, barbarian, natural, etc. The types of guild armors and weapons can be designed accordingly. The more guild types there are, the better differentiate between guilds
