CoH1 and CoHO had questionable 2v2 balance; 3v3s and 4v4s were completely garbage in terms of balance, and were never played competitively. The same goes for games like Starcraft, Warcraft, etc.
You can enjoy team games more than 1v1s, I never said you couldn't. But there's a reason the vast majority of RTS competitive play is in the 1v1 space, just like there's a reason the vast majority of MOBA competitive play is 5v5.
Actually COH1 was pretty well balanced for 4v4 (most of the time)
But not on all maps and only annihilate mode. Just changing starting position from top to bottom on most maps would turn pretty well balanced map into 7 minute absolute romp. Mostly because of cut-off points, position of houses and most importantly you cannot run around map capping and de-capping points like in 1v1. Once you lose first engagement for point its extremely hard to get it back. Hence why 4v4 automatch was total failure in VCOH.
As far as balancing 4v4, it's a lot easier to balance then 1v1. Most of balance issues that are breaking 1v1 balance can be overcome by team builds and strategy. 4v4 only needs to be balanced with sledgehammer to get it to decent state.
However, units need to be designed with 4v4 in mind.
Problem in COH2 is that one army has extremely strong mobile armor and lethal AT infantry while other side has gimmicky slow moving armor that either needs combined arms or be set up in ambush to be useful. Add to that non-lethal AT infantry.
Tho both designs are deadly in 1v1, it's pretty obvious which massive shortcoming, team with durable mobile armor, will exploit.
That core design can never be overcome with tweaks to balance COH2 4v4.
As far as competitive 4v4, I completely agree. Most people who play 4v4 will go play 1v1 and 2v2 if they feel like being competitive because 1v1 just feels more competitive environment and not many games have truly balanced team games for competitive play.
Most of my COH 4v4 buddies and I did so.
for inevitable 4v4 haters: Most people I played 4v4 were top 200-300 1v1 players so don't even start with bagging, in all likelihood it was you that was noob. Thanks for restraining from unnecessary flaming.
