yeah it is worth your time and effort this armor will last your from 24-30 which is a good thing and fortunatly it sell fairly uickly depending on which server ur on
30? It really depends on the job. If you're a WAR or PLD, you'll be just fine with the "cheap" set (normal Chainmail set me back 17k on Remora) and save up for the Eisen or, if you're really flush, Kampf lvl 29 sets. Even the NQ Eisen > Chain +1, and it costs a HELL of a lot less than the Chain+1 pieces. My Eisenbrust was only 11k at AH, and it was the most expensive piece in the set. Of course, Chain+1 does sell fairly quickly so I suppose it wouldn't be too much of an investment.
Anyway, if you're reading this far down in posts three years old- read the various equipment guides for your job and make your own decisions.
