I have a republic character and unless we make a premade, a group of Empire ... all who are Sorcerers, Assassins and Operatives seem to waste us constantly. One group, I went up against it was:
2 Operatives
3 Sorcerers
2 Assassins
1 Juggernaut
They defend the three guns on the Alderraan Warzone with a 2-3-3 split ... even when we brought 5 we barely could kill one of them. And this wasn't a premade Empire which tends to be even worse.
You think it is bad Empire, try Republic.
