In Patch 12.7, Pantheon's tap Q got some changes by increasing his Q range by 50 units (550 -> 600) and lowered the width from 150 -> 125 units.
In Patch 12.10, however, there was an undocumented revert of these values and so Pantheon's Q tap range is back to 550 instead of the 600 value it should have now. Below is an image taken from LoL wiki that has listed this Q range revert from 12.10, listed as a bug.
