Help regarding missions
If this has already been answered, please forgive me but I need some help regarding mission portals. That success meter that shows up after a mission; what is that based on?
For example, I had a Lightbulb mission (um, at least I think they are called that) on the hard portal and I selected Optimus Prime, Soundwave and Lockdown. Both of them except for Lockdown got 3 stars even though I matched the icons. So why did only Lockdown get 1 star? Any suggestions? Is this somehow related to the Transformers' upgrade levels (as my Lockdown is only level 4 while the others are at Level 10)?
