One question though. What does your 6* roster look like? Honestly, keep playing consistently for a couple more months at you will hardly even be thinking about 5*. So the investment of AGs and sigs becomes irrelevant pretty quickly. At the very least, wherever things overlap between 5* and 6*, focus on the 6*.
Tech - Hulkbuster
Cosmic - Medusa
Generic - Doom? Better be absorbing man or serpent
