the random loot tables, even preshroud, has/had the opportunity to drop weapons capable of more damage than shroud craftables. Changing shroud weaponary in order to drop mob hp is silly; b/c those lucky few with high + holy greater banes, or element greater banes will rule the day instead.
the nice thing about shroud weapons is that they eliminate the need to carry buttloads of specific mob weapons, trading in a tiny bit of damage for those with uber weapons, and gaining a few points for those with less so uber.
there is a heavy grind associated with the shroud, might not be as noticable for some with multiple toons. But try grinding a tier 2 weapon with only a single character, and w/o trading or purchasing ingredients. The weapons are appropriate for the grind power level wise.
Furthermore, the whole argument that recent mob HP inflation is due to shroud weapons falls straight on its face by the simple fact that only a handfull of monsters recieved this increase. If shroud weapons were a serious consideration, then the kobolds and monks and all the other jazz besides the giants (and elementals in SoS) would have boosted HP.
