It would be nice to have more than 10 guild ranks in the guild. In large guilds that do not focus on only one thing this makes it a little hard to organize the different group commanders in the guild. I would love it if the ranks where not restricted or if the number was increased to 20 this would allow for more groups with in the guild. I would also like to see more icons to choose from that are a little more varied as so you can very easily tell the difference between them. Now in a list of over 300 – 500 it makes it hard to tell the difference with some of them. Not complaining just making a request if its possibility I would love it. I find having more positions let the different members, and groups feel more part of their guild community.
More guild ranks
And also increase maximum guild capacity, there are quite a number of guilds which have to make branch guilds because they have exceeded the 500 limit. GW2 is constantly growing and so are its guilds. A limit of mere 500 is way not enough imo.
