It's Farstriders that have been the least developed. But the most prominent characters have been Light users and rangers. I guess if you look at Thalassians as one race, then this may hold tree, while the blood elf sector hasn't shown much far strider ranger activity, it's bene alive amongst the void elves through Alleria and the high elves through VEreesa as well as the Darkfallen through Sylvanas - they really dominate every Thalasisan character, including every blood elf one.
But seeing they aren't blood elves, if you only view htem in their separate camps then you'd be right.. but still screen time has been a lot more for the Light wielding Liadrin than any magister, and even Lor'themar (a ranger) who's had increased time has bene nothing about rangers.
Personally I just don't feel we are connecting to the Farstriders as much.. the magister connection is there, but it's passive compared ot the humans despite it's dominance in the background (similar to the Order of Elune in much of the night elf portrayal in wow), it's there but always backseat to a druid (night elf) or paladin (blood elf)
