I kinda feel it too. RA is such a tank game, I only see people build heavy and medium tanks most of the time. Nobody builds artillery, rangers, tesla troopers, etc. Heavy/Medium tank can do anything on regular maps, infantry can easily be runovered (except shock troopers but players still prefer tanks since shoc troopers cost almost the same), base defense can easily be outnumbered, aircraft do little on tanks but take longer time reloading and being vulnerable to tanks while doing so,etc...
That video doesn't really prove anything much other than how infinite ore maps ruin the good C&C gameplay.
