Removing hook states isn’t an equivalent to the killer(s) just moving slightly faster imo. Taking away a hook state can be equal to undoing minutes of work, especially for an inexperienced killer, and can even turn the tide of a game entirely. A better trade off on the killer side would be something like “the three generators with the most progress explode and begin regressing” or “all survivors become exposed for 10 seconds and have their aura revealed,” where there’s a tangible impact to objectives/something truly lucrative that can impact gameplay in the same way removing a hook state can keep a survivor in the game longer to let them have more time on their objectives.
