First, Im a vet player with 38 mill SP. Ive tried a lot of things and i can say that is very frustrating that i cant make the Amarr commando (refered as Ammando from here on) perform as steadily and efficent as the other commando (tried them with alts).
Also is so annoying to get overheat all the time unless u bring a non-laser weapon which in my opinion wastes the porpose of the Ammando bonus.
Last but not least, i like to make an AV commando fit with it (1 of its mainly porposes) and the more efficient weapon ive used so far with it is the assault combat/rail rifle and saddly is not even weapons that benefit from the Ammando bonus.
Maybe im doing something wrong with the Ammando, it needs a tweek or is just a waste of time.

the builds ive tried so far.....

Ammando STD:
-Proto DMG mod
-Proto Repair / ADV if trying to use the Assault ScrR
- ADV Swarm or Laser
-Assault Combat Rifle / Assault Scr Rifle or ScR <------- which has given me the worst results
-Nanohive

Ammando PROTO:
-Proto DMG mod
-Proto reapir
-2 Proto Armor Plates/ 2 ADV Armor Plates if Proto Assault ScrR or Proto ScrR
-Proto Swarm or Proto Laser
-Proto Assault Combat Rifle/ Proto Assault-Tactica ScrR
-Nanohive

Amarr Commando is so underrated , not that it's not in need like all commandoes but it is under rated .

Hell , all commandoes need something but no one listens .

Just like logistics .

I always keep the adv and pro rep / ammo hives on me .

Does make a difference .
