I use 5 x ravager (pvp), 5 x hunding (craft) and one drop shoulder on my nb.
5 x martial knowledge (drop/pvp), 4 x healer (drop) and 3 x thorug (craft) on my sorc.
This game is unique in that all sources of gear is valuable. It is not like most mmo's where either crafted or drops become irrelevant in the endgame and the devs should be given a big kudos for that.
They did it too in DaoC where drops were best in certain slot and crafted were best in other slots.
It is up to us players to play around with combinations of skills, stats and gear to make the best and most fun build suited to how our personal preferences in playstyle meet the game environment.
