A few years ago I was in a corp and they taught me how to do Abyssals. They provided me with this fit since I liked using the Catalyst Navy Issue, and they suggested Calm Exotic to start with:

They gave me a list of skills to train and taught me how to most quickly and efficiently defeat the enemies in each pocket. I went in with zero experience, and it was so easy, genuinely one of the easiest but also most interesting combat experiences I'd ever experienced! In fact I had to quadruple-check with the corp members teaching me that I hadn't missed anything because it was so easy. I must've made 1 billion in just Abyssals with just that fit and just Calm Exotic. It was fun, engaging, and easy. I could literally watch YouTube videos on the side while I mindlessly did Abyssals, it was that easy.
I haven't been in a corp in years, but I came back recently with a fresh character, trained up all the same skills, purchased the same ship, constructed the same fit, bought the same Calm Exotic, did everything exactly the same as my past teachings. I use the same strategies as I was taught, same order of operations, same distances, same "kiting", 1:1 same exact EVERYTHING... for some reason it's the most difficult thing ever??? I got past the first 2 pockets with 0 shields, 0 armor, 1% hull, and a drained capacitor. I took the extra time to let it repair and regenerate. In the third pocket I was greeted with two cruiser-sized enemies who literally one-shot me. I can confirm without a sliver of a doubt that my weapons are doing the same damage as before, so it's not like my damage isn't adequate. My shield, armor, and hull amounts are exactly the same as last time, and so is my capacitor amount. I double-checked, yes I did activate Calm Exotic and not any of the more difficult types.
I want to doubly reiterate, I know for a fact I did everything 1:1 exactly the same as I did before, at least I'm confident I did. Skills, ships, fit, actions taken inside the rift, everything. My damage output was identical, but my capacitor now drains nearly instantly, which is weird because I very distinctly remember a past corp member saying "I know you like cap-stable ships, so I found this fit for you", so something seemed off when I noticed it wasn't cap-stable. My shields and armor go down in just a few hits even with all modules activated, which are supposed to, as the fit's description says, tank the armor damage.
Am I missisng something? I'm VERY far from an inexperienced player, so if I did something wrong, it's because something has changed or it was a very small mistake with very big consequences. I watched a YouTube tutorial on this, and everything they recommended, I already knew from my past training. Did some game mechanic change or get nerfed anytime in the past ~4 years?
Edit: Before anyone asks, I wrote this post by hand. I write large walls of text, I'm sure my post history is good evidence of this.
Edit 2: After staring at fits for a while, it hit me - I didn't run Calm Exotic, I ran TRANQUIL exotic! That should explain the difficulty spike! I'm off to grind up money for a new fit, I'm so sorry for wasting everyones' time!
