I use them all the time, it's either falls or jaegers in 1vs1 from me as I prefer mining to spending all my muni on fusilier g43s.
OKW cancernades are freaking amazing. Just those alone are worth having a squad for.
I mean is that really the falls or is it the cancer nades?
Jaegers are stupid good, especially in comparison to the much more expensive falls. Cancer nades help on top of that
