I don’t have demos, but I have some gameplay points: at the first objective, move the gdf spawn closer to the objective. Currently the GDF has longer travel to it, and it seems close to impossible to prevent the strogg rushing the first objective (they get a plant before you get to the building. They should meet in the lobby at the same time.)
At the seccond objective, as already discussed, strogg can use a teleporter (or a tormentor) to reach the hack before they should, thus giving the GDF too little time to fall back.
Same thing is the issue at picking up the data brain, you can pick it up immidietely after hacking, which encourages camping the objective prematurely. Give acces to the train station, so the strogg can get the forward spawn, but don’t open up the mall itself until 30 seconds after the hack is completed*. (Also, I am pretty sure on the match we played lae yesterday, that I recieved no message about the databrain being picked up (which in turn probably was because it was picked up very early.))
*This should be be done differently, if the objective I talk about just below is implemented.
As soon as I get my scanner working, I will send you the 6 floor vertical construct objective (between the hack and the databrain, in the unused building to the south (and, yes, it would be extended vertically)) I have sketched out.
