"If we keep the Thor, we are currently experimenting with an anti-air spider mine that would give the terrans a way to get some factory-built anti-air into small places that a Thor has trouble reaching (like near your minerals). Whether this is meaningful, considering terrans have marines, is still in question. We are also experimenting with an extremely long-ranged terran missile launcher that can be used to break siege tank lines to make terran-vs.-terran factory-based games more dynamic."
