the point isn't to give them impact. It's to have them all at 2\* as 3-6\* RUTs are pretty common from my limited experience playing (2 months in)
I spent most of that sub on my Colossus, who just needs to be level 60 and will be ready for T2 advancement.
I had extras so I got Magik, and old favorite, and had 8 days left after getting her to 200 stored x genes, then decided that the other paywall x gene characters should be ready for tickets so the collector in me doesn't feel he has to buy another sub down the road.
So, which would you choose?
