For crafters i just used my lvl 60 melded ironwork gear and had no problem getting all my classes to 70. Only pieces i got was lvl 63 gsm/crp weapons and lvl 65 body because didnt have lvl 60 weapons and the body was alittle better then ironworks and i like the way it looked. As for gathering i got 62 because didnt have 60 gear then I got the 65 hq gear melded with 2 gathering 3 for each piece that could hold it and was able to gather every node to 70 again with ease.
