I went through the wiki but that can be a bit confusing if you never played GW1 so thanks a lot for your summary! And yeah, I guess if guild missions are something around those lines they have the potential to be fun. Although if they're planning for ppl to do them as a guild group that means it must consist of open world content, so probably would be something like the daily achievements but for guild groups (do a dragon event, do X number of events, capture Y number of towers in WvW, etc.)... I hope it'll be a bit more fresh/exciting than just that
