I think that factory plopping in the lake on this map is probably bad play at the best of times, even when you get away with it, since you are tying yourself down to defending an area of the map with no metal points. That is just a personal opinion, though.

On any map, if you run so far forward to place your factory that it gets mobbed by enemy units before you can make units of your own, that is obviously pretty bad. Somebody who consistently did this might eventually force the moderators to intervene.

I don't see this one game as modactionable, but do not interpret that as an actual endorsement of how you played this one.
