Hmm looking at the Slicer and Infiltrator specializations, it seems a bit strange that the Slicer is potentially stealthier out of the box than the Infiltrator.
The slicer can get 2 in Stealth while the Infiltrator only gets Stealth from the Spy Career.
I know the Slicer Specialization is from EotE so it will not be changed, but I think the Infiltrator should have Stealth as Specialization skill.
I also find it strange that the Commando does not have the Stealth skill, but that has been commented upon by others before.
Just My simple opinion.
