Ok. Is this legal and allowed?
The Tau Air Cadre for the most part has a minimum speed of 1.
Now, this means that the entire list can essentially hover. By yo Yo ing, speed is shifted one column slower (speed 0), but never causes a stall.
So we could have Tau fighters who stop dead. The tiger shart ax 0-1 who stops dead battering ground defences repeatedly, and if anyone drops down to deal with them, a whole face load of air to air seekers.
How else might this be exploited? If it is in fact legal.
