Some good feedback on this thread. In answer to the question, how do I deal with speedy teams? The honest answer is I take a lot of abuse from them. It tends to go something like: IG86 or 88 get a faceful and possibly fold before they even shoot. GG gets hurt and either HK or IG100 taunt. Then it's return fire. I'll hold off any AoE until GG laughs then unload with everything, targeting their healer first and using GG's basic against counter hitters.
To be fair, I prefer a fluffy all-droid team but there's some good sales pitches here for JE. I might need to max him out and give him a second chance but I'm loathed to let GG go.
