What they need to do is bring up the 8v8v8 modes and start building from there.

The ShB changes on mobility were also a double edged sword because every map goal mechanic is not able on its own to keep every side from staying in massive army blobs anymore, which was less the case before because you had to spread around to cover multiple objectives, and it wasn't possible to zoom across the map like you can now. But yeah, it was also a lot less funny to respawn from death and spend minutes to go back to the front.
