Your custom unit get's two shotted by Mercenaries with 100% hit and twice as much speed as you and on top of that they dish out over 10 points of damage with one strike. There is no luck. If anyone needs luck it's the Jagen unit. With no luck he will die.
Got back into Witcher 2 since Torchlight 2 doesn't want to start. Pretty good.
I am the only competent Engi player ever. Doesn't help if the other 2 engis upgrade my stuff when they have absolutely nothing set up yet since they just bring attention towards my stuff.
