This is less of a bug that needs to be fixed and more of a criticism of mechanics with a suggestion on how it should be different, as what is happening (how probes build compared to the other races) is intended.
Probe micro has been part of Protoss mechanics since the start. The micro can be seen in use at all levels when shift queuing multiple structures in close proximity: build, M-move out of the way, build, M-move out of the way, etc. It’s simply a unique characteristic of the Protoss. The only alternative is to leave an escape path.
Because the development teams don’t collect feedback/suggestions from the support-based forums, you’d have better luck posting in one of the discussion forums. Either Protoss Discussion or General Discussion.
