I use just the worked dragonwing cloak because of my low base wisdom as a shaman. I'd rather have this heavy dragonwing cloak than a hiero, simply because wisdom gives great mana at 55+ and with +9wisdom items its actually feasable for someone with only 90 base wisdom to max it out and retain some ac and resists.
The higher ac and wis items you get the more you can use those other items as bonuses like blue diamond gear etc. I can barely get my wisdom anywhere near 200 at lvl 59 because of my base wisdom being 90. Well, lemme say that, I can barely get my wisdom close to 200 without putting on absolute crap for ac. This is a very good cloak, noone can deny it. We all know its not the best, but so what?
