Well there is the issue, GS only seems to use iLevel of an item, some iLevel 200 items for certain classes work better than an ilevel 245 item (due to procs etc) and so the ilevel in some cases makes GS misleading and as you said, currently I could have a 5k gs with no enchants which really makes the gear equivelent to a much lower iLevel once it is missing enchants and gems.
