I am going to make a prediction and say that the most undervalued unit are the Elite Jet Troopers. they will slip under the radar and be splashed into every trooper and Sorin lists. I dont thein taking 2 is the best option, just 1 is enough.
I am a little chocked that people dont see the potenial of this unit, for 7 points you get a 3-dice attack unit (basicly) and for 1 point more you get rerolls on those dice. They have a lot of health, they can generate evades to stop surges (add Zilo to it then), a lot of good command cards, the ability to retreat or advance after their attacks. I can see them finishing off some units that are at the front of the enemy making it harder for the enemy to hit back.
Actiavte them last and first and burn your enemy with 4 3-dice attacks.
Once your enemy starts killing these, they wil take their time to die completly, and while they get shoot your elite Stormtroopers are there to kill stuff also.
Among all the large figures coming, I think these guys will be a thing.
