I agree wholeheartedly to the post by Zya. My guild has over 100 members, however, only 20 or so participate on a regular basis, that I know of anyway. There is no way to deem a guildmates participation and therefore, contribution, to the whole of the guild. So frustrating. I am co-guild master of a level 25, over 900 member guild in wow, yes wow. The tools provided in WOW enable a guild that size to run smoothly. I expected even more from GW2, and have been sorely disappointed to date. Developers, How can you continue to ignore such a huge shortcoming in your community. At a minimum are log in times and ability to see each other on the map, of course with the option not to be seen. I still have hope of improvement but it running thin.
