Part of my goal in theorycrafting an improved MULE was to bring the MULE “back from the dead”. Put frankely, its not good gameplay to have things constantly dieing apart in the players base. I understand why the MULE has a 30 second timed life but it leaves a bad taste in the players mouth. To make matters worth macro is about building up your base and making your army bigger, having players witness their assests fall apart every 30 seconds is the antithesis of the feeling you are trying to promote. It gives players unnessisisary bad feelings and deminishes the enjoyment of macroing. It may be appropriate for the nighthawks turret but not the MULE.
I remember when the MULE first came out. One of the most repeated concerns was that it didnt fit well to have a robot you call down from space that just runs out of batteries and dies. It didnt seem logical or economical for aTerrans to invest that kind of money in a mining machine only to give it AAA batteries. Maybe if we used the cold fusion for more then just chilling beer
Now Starcraft 2 is certainly allowed to bend the limits of disbelief. For instance, timed life units falling apart is fine for the Nighthawk's turrets. But why have a unit as prominent and important as the MULE fall apart especfially when it fits so poorly for the unit's role and there are alternative and cooler ways of ending the units life. At the end of its timed life a Remote Mining MULE would transform into a atomospheric escape pods and launch back into space. The lore would be that MULE needs to return to the orbiting space station for refueling, maintenance and processing of its minerals payload. Not only does this enhance the units charector it also draws from portrayals of space mining in literature and movies.
In addition to being less awkward lore explaination there is actual gameplay benefit to having the MULE fly back up to space when it finishes its tour. Consider what happens with the current version of the MULE if your timing is slightly off. Currently if you misdirrect the MULE or order it to do something and its rhythm gets thrown off then that 2 second delay could mean the MULE dies right before returning its last batch of minerals to the CC. Over the course of the game this could add up to allot of lost minerals. And that’s assuming that the way the timing works out now a MULE called on a mineral patch wil finish its last trip right before it dies. For all we know it could be that MULEs never finish mining and always drop their last shipment. It is extremely bad for player enjoyment to lose minerals just because the MULEs cycle happened to be thrown slightly off.
Even if the developers dont want a Remote Mining MULE, I would still hope they would at least consider making the MULE transform into and escape pod. This gives a much better impression than just running out of batteries and falling apart.
