May I ask what your guys reason was to play as an elf?
Most people seem to like human PCs better, so what made you roll a Lavellan?
My Warden was a City elf because I found their situation in the world interesting and the origin was good (Shianni & Soris
).
During the game itself, the race kinda grew on me, because of the lore, the dalish legends and the fact that they were just so much more interesting than the usual ("boring") humans. Missed the option in DAII even more than I thought I would, and therefore rolled a Lavellan in Inquisition.
I don't know why darwes don't appeal to me, and I have a qunari PT on stand by, because I do my second Lavellan right now 
Edit: Hope that all makes sense. It's pretty late here!
A juicy question, indeed.
On my part it's two-fold: first, I had my heart set on Solas since the start and as soon as I learned he would be a LI option, I was sure; yet, that by itself is not answer enough, since I would have gone with Lavellan for a first playthrough no matter what. (And after having finished the game, I'm thoroughly convinced it was the best decision ever, there's just so very much in DAI that makes playing an elf a totally deep experience, and that does include the Solas romance.)
I agree with the sentiment that the Dalish grew on me, it became kind of personal after lots of DA playthroughs, even when I wasn't playing an elf. I developed a thing for elves. My canon became a female Cousland for DA:O, but elves have been my canon race since forever before that even so. The why of it goes beyond the DA franchise in general - I simply identify with the Elven archetype.
Plus I'm madly obsessed with concepts of things and civilizations lost, the tragedy of a people or an age, the magic that slumbers deep in the modern world. Ancient ruins, places of exquisite beauty and immortality that have been squandered, crushed and destroyed? Ooh. Ooooh.
I like dwarves, too, their loss and history draw me, too, yet if I had to choose between the beauty of a divine forest and the heart of a mountain, well, I'd lean towards the forest. Aesthetics is a thing for me, and dwarves I find too... boxish. Though fascinating.
On an even vainer note: the ears. I really like the ears.
