Well from what I've seen so far DA4's story seems to be exactly about Tevinter and the Qunari. I also am very interested in such a story. Furthermore, the art showcases a strong female Qunari character as a possible companion.
The Qunari are possibly my least favourite race in DA. It didn't help that they altered appearance so much between Origins and Inquisition.
Having said which, my current DA:I character is a female Qunari mage.
Yeah I have a love-hate relationship with the Qunari. And for me it doesn't help that the Qunari are portrayed physically to be so immense to be somewhat unrealistic. How does any other humanoid even come close to surviving, let alone competing, with such massive brutes in combat? And don't even get me started on the mechanics of Qunari-human/elf sex.
