Here is the idea: give to hallucinated probes from sentries the ability to mine. However, they wouldn’t gather any real mineral/gas to the Nexus: only the animation would be real. Moreover, they would collide with normal probes as if they were real when mining.
Why is it cool?
Because hallucinations are an amazing idea but they are sadly underused. My suggestion would allow to a protoss player to fake the fact that he is fully mining his natural base for example while in reality, he is going for an aggressive play.
What are your thought about this? If you like the idea or have suggestions, please react to give more exposure to this post and have the devs read it.
