So after last night's (9/21) test, I was thinking about how easily I went through the entire third tier on the current arena. In the third tier, as we played, the center point was the same value as a 2-chain token perimeter point, which is much harder to pull off. Combined with the 4 point duration, it was way too easy to blitz through the endgame.
I propose an alteration where the center point does not scale with tier, but just goes to 2 points in the 3rd. Chain tokens will grant more points, but you have to brave the edges. This incentivizes the center, but makes a four point maneuver phase less likely.
