It wont pay like crazy though. There are plenty of examples of CG offering terrible rewards constantly. GW still offers lvl 42 regards at lvl 80 (cool). Credit event was initially way better, months before they made worse (way worse). Daily activities still pay nothing for credits. Cantina and missions haven't improved equal to the cost. All the credit rewards need to be scaled up to the new lvl 80 costs (lvl 90 is coming. Can't imagine how much worse it will be). Plenty more examples of poor rewards throughout the game. I doubt this will be worth it either.
Imagine a 5 man team of scoundrel heroes. Most probably don't have any, aside from a low chewie. So it takes 25-30 million for the team for the event. Event is once per week and pays 1 million. That's 30 weeks to see a return. What if it pays 500k? That's 60 weeks. Even with a 3 man team, that's still 15-18 million. So a 15-18 week or 30-36 week return. Not promising
