DRG at 70 is more like what monk was at 60 and monk at 70 is now more like DRG at 50 lol...

For me personally DRG and NIN are the most fun at 70, then SAM and way far behind is MNK.

RDM also does auto attacks during instant casts so while not really a melee, it does help playing it like a melee lol. Not sure if it always does or not but I do notice them pop up.
