Its got nothing to do with what is smart for your business or how many people play a particular game mode. The problem is it's just NOT POSSIBLE to balance 3v3 and 4v4, those game modes are about who can spam the most units faster then the other team, simple. 1v1 and 2v2 actually have some strategy involved.
You Sir, have no idea what you are talking about....
I actually spam a lot more in 1v1's, and strategy? Its quite different. 1v1 its all about capping, denying points and resources, outflanking and having counter for expected unit at right time.
After a while, it becomes more of a specific set of tasks that I try to do in quickest possible time. Get to this house before my opponent, send my unit here to flank mg or ambush vehicle that will come in next 30 sec... organised chaos
now if you think that simple thing like de-capping point in 4v4 is about spamming units and doesn't involve strategy, all I can say is HAHAHHAHAHHA AHAHHAHHA.
try taking a point from someone who has it guarded by anti-infantry, AT guns and ranged units. You can't just retreat and go cap other side of the map if your opponent locks down area by HMG, you have to find the way to kill it.
You can't just outflank it, and spamm infantry to outflank it. It requires a lot of strategic planing, less chaos. More like a chees game, I won't even mention that in 1v1 you don't have to plan for your teamates shortcomings, or being prepared to fight of 2 opponents at the same time, until help arrives.....
Different strategy, sure. What you think, well you would be terrible noob 4v4 player
As far as how they are going to balance it, I do agree there. I can't see easy way to do it, with the way two factions are designed......
