Based on the feedback i got here and at other boards i made following changes:
Tusken: Riffle ammo limited
Delta669: health increased to same settings as regular troopers
Geonosian: fly range increased and itīs a bit more stronger but still weaker as standart soldiers
Gamorrean: shield sound added and shield duration time reduced
And the Tusken recon droid is on the cut list. I want to replace it with a different weapon and hope to fix the Delta droid freeze bug (possible memory related)this way.
So any suggestion?
