The ideas sound very well, we will feature guild Strongholds which will be conquerable by other guilds.
I like the donation system of funds, because I have been in many guilds, in many games, and there is always the problem with not having guild funds or mats. Not sure if daily is the best approach, maybe weekly or monthly, you have to pay a fee in order to remain in the guild , and because some people tend to enter and leave guilds frequently, there can be set a penalty if you leave the guild during the first week/month.
The other stuff is fine, it'll be nice for people to be able to enter the Guild Strongholds and visit/spy on other guilds.
