In many games there are features that are made for capturing. So why not make maps with something like it. Now most common mod used is BA and it has t1 revive bots, from what i saw dead units can be placed on maps, this gives easy way to make strategic buildings to be capturedby reviving (tactical nukes, E structures). Coms have capture by default.
Or maybe some LUA stuff that allows all builders capture/revive certain structures/units made only for to be used this way.
Speedball has map based building so making map based unit for capture/revive should not be that hard.
Sorry if this was mentioned before never saw any topic that is close to my idea.
