Ok, so i'll preface with cards aren't officially out yet and subject to change. But what have you dreamed up that's going to be trollish or potentially game breaking?
My own examples-
The atst suppression bomb
As was pointed out in the so far, vehicle weapons for the most part aren't unique or limited unless stated in the rulebook. Triple mortar Weiss on the atst parked in a corner of the board, dropping 3 suppression just about anywhere every turn anyone?
The sons of Anarchy Speederbike gang!
2-3 speederbike units all with comm jammers doing circle work around the enemy commander.
The guns at high noon atrt showdown
triple atrt with rotary blasters..... 15 black dice with surge to crit conversion! nuff said.
Vaders zombie legion
Vader + several snowtrooper units. The snow troopers all stick to range 1, using vaders unbreakable leadership and can advance as often as they like, needing to be wiped out to be stopped. For the extra lulz add concussion grenades and flamer heavies to really up the pressure to stay out of r1, and for maximum effect also add veers to give 2 units free aim.
List me your cheese!!!!!
