Power creep at 100% now

Seems odd there is such a difference in only a few months. Wiggs is pretty much dying out. There are still a few, as I listed, but they are in the minority. They aren't the best combo even in their own faction anymore. I guess those few extra months was the difference in being able to acquire Chirrut in the tournament or not?? Because a 4 star Chase is pretty much better in every situation than a 7 star Wiggs.
