You really can't expect more than one good set per role and expansion. For tank we got the Asscreed looking ilevel 700 set (best looking set in years) and now we can't expect anything good until at least mid next expac. For healers we had the one from the first 24man in EW that is okay and before that the one from the last 24man in ShB which is great (combine the top with the E7S leg item), so we should have one coming up relatively soon.
