[The Shortest Path]

The patch 2.0.3 notes are referring to a bug that existed where CP would occasionally fall off on deselection, it certainly did not work like that all of the time or even most of the time, just in rare circumstances. Note the "should", because the bug still existed in early BC until it got fixed again.

This is absolutely, 100% an incorrect implementation of how it worked in 1.12.1. There are probably rogue gameplay videos that would show it as such, but I'd need to do quite a bit of digging.

It was definitely NOT a bug that was corrected in 2.0.3, since Blizzard had already changed the way CP were handled with patch 1.4, in which they clearly stated CP "will" be lost if a different target is deselected : this clearly states it was intentional from Blizzard, end of story.

There are, indeed, tons of Rogue videos from pre 2.0 confirming CP should be lost upon selecting a different target.
