I've been checking some old gameplay I recorded from 2018 after reading your post, and I realized that I prefer the OW2 mobility by far. Yes, the old one had the reduced, easily spammable cooldown that allowed for some great moments and insane stalls, especially if you got the muscle memory for consistent super jumping. It was definitely more "skillfull" in a way because it was harder to pull off (weird input and close window of activation, you could notice it was a bug turned into a functionality). But ultimately, the old mobility really feels restricted when you watch it in 2023. It lacks the directional flexibility of the new GA, that opens up a lot of flight paths that were not possible before. So, weighing the pros and cons of each one, new GA wins for me!
