Considering the elves have been fleshed out with each subsequent addition to the series, its kind of hard to say Bioware doesn't care about them. [Doubly so when you compare them to the ignored dwarves, or the lulzy trainwreck of the Qunari as of DA2/DAI.] You might not like the direction Bioware chose, but that's a different matter.
Thing is with dwarves we got to see quite a bit from Varric, bart, and Doogal and if you didnt have nath live in DAA you got the dwarvern brothers deep roads mission
dwarves are simple they like tradition and willful stubborn to let it go.
qunari... i dont even know man.
Between Sten / Kirkwall + tallis / Bull i dont even know what is going on with the qunari
the qunari seem to be having identity problems but different to what the dalish are having D:
