Most Yak drivers have little skill or understanding of their bird. Yaks are not commonly flown. As a PonyD driver I'm fine with them. They tend to be very aggressive, easy overshoots and burn E with unnecessary near blackout turns. Play E and overshoot until I can get them verticle, which is the game changer.
At least that's how most seem to go. Some actually know what they're doing.
