I have to agree on that, to me its not about winning or scoring high, its about having fun.
That dont mean I cant appreciate high socres and winning matches.
To a type A personality, winning and having fun are the same. I live by Conan's credo.
"What is good in life Conan?"

To crush your enemies, see them driven before you...and laminating the women. 
Why for gods sake would you want to laminate the women!
to the original poster.
The answer is to play a VERY specific way.
to those who think it is about sacrificing your teammates, i present the following screenshots.
The reason everyone on the team did well was because they kept returning the base after every fight, and since--- on average, ever player was doing better because they were working together, and the teams were accumulating money quickly, the game becomes super one sided.
Because of how good more expensive mechs are vs the cheaper mechs, and how the in game economy works, once one group gets momentum the rest of the group can gain from that and the enemy can never catch up.
Even if only 2 people on one team are working together you can get this phenomenon.
You should have seen it when I had 2 friends to play with
