This dev note is insightful
This sort of confirms to me that decisions are made too hastily, a singular patch which is not even live, it's a PTB patch, is not enough to properly test something unclear right away. The obviously overpowered stuff should be addressed, but this was mystery area at best. And what do you mean, stacking basic attacks recovery? Do you uh, know that Diminishing returns exist? Stacking more that 2 is already less effective than just 1. Additionally, connecting shorter chases with perks is far fetched. I am no expert, but in my eyes shorter chases usually signify people either being bad at looping, or simply not adapting yet to the attack recovery via greeding the distance they think they can make.

52.5% shorter cooldown with Dark Arrogance and STBFL was not so much an issue on the majority of killers, but on Freddy and especially Clown it was a genuine issue. It wasn't about the survivor being bad, it was about them getting absolutely nowhere before getting hit again. Here's a clip I found from DStrike. Granted it uses all 4 perks for 60% faster attack cooldown, but the difference between that and 52.5% is not that big.

Granted, the DA nerf is not what I would have liked to see, as I think it may possibly be worse than before the PTB due to the stun duration, but it was indeed a problem
This is... A clip with bots...
Could it be problematic? Maybe, nobody can tell because it was not enough time to know for sure. Should the effect be completely removed? Absolutely not
Chases are the most interactive part of trials, so we made the Judgment to eliminate them.
The time a PTB is online is far more than enough time to understand basic issues. Hell, for most issues you dont even need to play. And good players will understand new gameplay within a few hours.
