While you're right that it scales, you're wrong about where it maxes out. It always maxed out above the enemies level by a bit. Hence why Crota on normal was even easier being 34 as opposed to 32.

Because Crota hard was 33 and you only maxed out at 32. It was easier because you could now do level 33 damage, even as a 34. If we go play Crota now, we will do the same exact damage as a level 33.

I was talking about normal mode.

Normal was easy as a 31. You're still gonna do the same damage now as they would. Same with VoG, normal AND hard. You will currently do the same damage as a 30 and 26
