I would argue against the Automatics specialization in general. I understand that this is a game, but my reasoning is that the skill doesn't transfer from one weapon type to another, just because it is capable of Automatic mode of firing.
Machine pistols share some commonalities with SMG's, but from that point forward, Firearms with automatic mode of fire are different in design and dedicated purpose. Therefore the specialization skill is not universally transferable from one type of Firearm capable of automatic mode of firing to another.
The handling, operation and reloading is different, the length of the barrel and range is different, the caliber and recoil are different in most Firearms capable of Automatic fire, so Automatics specialization is too general. Again I point out that Machine Pistols and SMG's do share commonalities and should be treated carefully.
A StreetSam takes specialization in Assault Rifles, gets + 2 dice pool bonus when operating an Assault rifle like Raiden, or AK.
A Decker takes specialization in Automatics, gets + 2 dice pool bonus when operating everything Automatic fire capable. Decker keeps the +2 dice pool bonus when operating an AK or a Raiden and keeps that bonus after switching to Automatic SMG. Streetsam has to use Assault rifle or loose the specialization bonus.
Will the specialization in Burst-fire have the same application among all the weapon types capable of Burst-fire, even tho one is a Pistol and second an Assault rifle ?
