EPTWhen you call down a MULE, you can only have it mine minerals. What if you could also use it help an scv to build a building faster? So once an scv starts building something, you can have a MULE help build it to reduce build time.
This furthers the style of the terran race because already you can reduce unit production time by adding on a tech lab to a fac or rax. Using a MULE to speed up build time seems to fit.
There are many interesting things you can do with this: Building a proxy building? Call down a MULE to speed it up. Mutas on the way? Help that bunker build faster. DTs coming and you don't want to blow a full scan? Speed up that turret production.
This macro mechanic has versatility without making you lose out on the econ benefit of a MULE. You can still get minerals by setting it to mine after it's done producing.
