Mobi visibility change

[wonderpug]

Harti, I could be wrong but I think you're missing a distinction.

Mobi sucks a visible unit and spits out into fog
Before: you see a unit magically move to the tile Mobi is on
Now: you also see Mobi

This is the situation where people were lobbying to make Mobi visible. His position is already being given away, so why not make it clear that Mobi is doing it and not dark magic

Mobi sucks a fogged unit and spits out into fog
Before: you have no idea this happened
Now: you see Mobi

In this situation, the opponent is gaining knowledge that wasn't available pre-patch. This is what Gonzales is referring to.
