I agree the update missed the mark.
We have toons like Chewy who are all about defense. Buffing defense here and there.
But defense is completely worthless! Who uses Chewy so they can buff defense? Or any toon just for the purpose of buffing defense? Defense would have solved the problem of the 1 or 2 shot kills.
Here the game had a perfect mechanic to fix total offense teams. And instead of fixing defense to work properly, they add another sort of defense mechanism, protection, that doesn't solve the offense problem.
