i think a better idea would be to add smaller wards to existing areas such as sea of clouds,ishgard, or dravanian hinterlands, etc. and unlike the larger wards these smaller wards would hold only 1 large, 2 meds, and 10 smalls. so essentially the concept would be "less is more". since wards are smaller this would cause less stress on the server. this in turn would also make it easier for them to add more wards to these smaller housing areas.
