Heroic plays like legendary?

Hello, I am new here. I don’t know if I posted this before, but a couple years ago I replayed the first two missions of Halo 2 Anniversary on legendary difficulty with a scarab skull and I think there was another skull or two I used, but I can’t remember what they were. After I completed the second mission, I switched back to heroic (my preferred difficulty in Halo games) and turned off the skulls and begun to replay the mission The Arbiter.

While I was playing, I started to notice that it felt exactly like legendary. I died alot more and faster than I usually do in heroic, enemies were resilient and fast firing like legendary. I checked if I was still in legendary but it said I was in heroic. It still didn’t feel right to me.

I have tried uninstalling and reinstalling the MCC and Halo 2 Anniversary and erasing the save data of the MCC, but none of it worked. Every few months I replay a mission of Halo 2 Anniversary to see if it self-corrected itself but it still feels and plays like legendary instead of heroic.
I thought I should mention that easy and normal play as they are supposed to.

To sum it all up, whenever I try to play a mission of Halo 2 Anniversary on heroic it plays tough like legendary. I am hoping for any kind of feedback on this issue and/or glitch and if this is fixable?

I mean to be completely honest I highly doubt you’re experiencing any kinda glitch or bug here. Heroic on Halo 2 is certainly no cakewalk and it’s definitely the most difficult campaign to complete on the higher difficulties. A lot of people will even say Heroic on Halo 2 translates to Legendary on Halo CE, which is somewhat accurate in my opinion.
