I am not sure I agree with this.
1. The smaller players starting with #8 on down gets some times under 1% as well. This means even if you raise it, it doesn't help them nearly as it would help the top 5 players when you raise the cap and further widen the gap.
2. This would make the game progression too fast which Tynon has clearly stated they will not remove the cap.
3. Do you really have 40 active banish participants all the time?
Based on what I can see, raising the cap to a significant amount only helps the bigger players and not so much the little guys (who are also mainly alts).
