Acceleration is broken?
The acceleration attribute doesn't seem to be doing anything. This appears to be the experience of others I've talked to who have experimented with leaving it at minimum, and it's also my experience. Furthermore, I went into open practice with a teammate where one of us had 81 acceleration and the other had 90 (while our speed and agility were matched), and based on extensive testing we could detect no difference whatsoever.
Note that I can only speak to EASHL and that this claim is not based on solid evidence, only the observations and the unscientific testing procedure above. To me the acceleration attribute seems to either not be doing anything, or its effect is diminished to a point where you get zero discernible benefit from having the maximum vs minimum that the EASHL builds allow.
