I wouldn't feel to bad about the trade you made to get your enigma. All those items you traded could be got through a day or so of botting (depending on your luck) where as botting for the enigma runes and armor to put them in could have taken 6 months (maybe longer). Actually because pub trading is just a huge pain in the ass if someone offered an enigma for those exact items on USWest ladder trade channel I would have taken it (if I didn't already have an enigma and this would be my first).
