Came from my post, really like most of these changes and the addition of Droideka :D
however I'm confused about what a Shield Charge does? Does it give bonus protection or something? I don't see any benefit to having the buff?
Also I think your HK47 unique Zeta is quite OP, I can see it maybe at "other droids gain this ability but at half the amount"
And just food for thought, I'd really like to see a cleanser and healer for the droids and separatists that isn't a legendary character. Maybe like a B1 Droid Engineer or something that can heal (repair) other droids. Well we need a B1 droid of some sort I think which would be nice :)
Nice work though I like it :D
