I need to decide whether or not to keep or replace these weapons.

Engineer Class: B1 Support Droid

-Health Buff (Similar to bothan spy buff)

Officer Class: OOM Commander Droid

-Defense Buff (Stock)
-Auto Turret (Stock)

The health buff makes sense, but will not be used very often.
The defense buff feels a bit boring for the Commander Droid.
Lastly the auto turret is nearly useless and dies quickly due to grenades.

Spoiler:

Does anyone have any suggestions for these three weapons? What could I do instead?

-I was considering the orbital strike grenade rather than the defense buffs, but not all the maps are outdoors.
-Detpacks have been replaced by a fusion cutter and the fusion cutter has been replaced by the pistol.
-Concussion grenades are already being used by the Assault Droids and Pilot Droids.
-Time bombs are used by Pilot Droids.

Id replace auto turret with the recon.droid for the oom cammander droid. Everything else looks good:)

The recon droid is currently being used by the Security Droid (Sniper Class) I might need to come up with a new weapon.

What's wrong with having two units with the same weapon?
