It's an interesting idea! I like the idea that you could sacrifice an upgrade point for a friendly bot that might die.
Just seeing AI vs AI might be fun! :)
Seeing as how the current AI has little, if any, sense of self-preservation, there's no way I'd waste an upgrade point on one. Assuming your enemies target it, it'd die within the first few seconds of a match.
This seems likely. :)
but not mk 3...
