Vastaya Champions Teaser Speculation

Just a page for speculation of the new champions. What do you guys think?

Personally, I believe the woman will be a mage and the man a bruiser by the looks of it. He could also potentially be a jungler sice he has 2 big talons/claws on his belt (was thinking something like Rengar, but then again, Gnar has bones too...)

However, I've been seeing many comments how these two will will be champions for bot lane, one support and one ADC. Seeing as how the attached sentence to the teaser is "She fights for the cause. He fights for her", it could be possible that the woman is an ADC/APC (who knows), and the man being a support.

Also, what do you think about Rengar being a Vastaya?
