Not sure if its just me, but I am very happy with all the new tradeskill items that have been added to the game in the past few months (carbonum, CAS, weapon upgrades, etc.). Initially I was disappointed with the implementation, but recently it has greatly improved. Now, if they could only increase the drop rate of certain items needed (soul frags, PPPe's, etc.), that would be a further improvement to a system that just continually gets better.
Keep up the good work !!
