Veers won't work very well in 3v3 without death trooper. I can get by without DT in 5v5, but not in 3v3. My troopers (zVeers, zStark, Snowtrooper) were a solid 65K going against a 48K Nightsister team and got totally owned. I mean it wasn't even close despite me having 20K more squad power.
The problem is Daka's stun - in 3v3 when modded for potency it just goes off too many times. Yes, I had the dps to take her out twice -- and zombie two or even three times as I recall. But with that zeta on Talzin there are too many resurrects to make anything good happen. It's basically like putting 3 troopers on 5 nightsisters.
So from there I think I threw maybe six more teams at them -- every single team had more squad power than 48K. All of them. I used a zPapatine lead, a zFinn lead, and a zBalista lead with Yoda. Every team failed. If modded proper that NS trio of zTalzin, Zombie, Daka is one of the most broken things in the game.
