Since 8.3 was developed and came out when 7 Stars were introduced, there is a 7* Attack Rating Bonus in 8.3 that rewards you for having and using 7* Champions. Act 8.3 still has the 6* bonus, which is less than if using a 7* Champion.
Compare that to the previous Chapters in Act 8, where you only have a bonus for using 6* Champions - as that was the highest that existed at the time. Now obviously, with how the Attack Rating scales, at the moment it's still a better bonus applied to your 6* R4/R5's than a 7* that's only R1 or R2 for now.
But to me, for the long term effects of the Story Content, should a 7 Star champion bonus also be retroactively added to the rest of act 8?
