Incase you weren’t aware of the ranking system it doesn’t depend on how many matches you win. It’s a point system that depends on how much damage you can do in the game. And rushing to destroy a base so the match can end in 5 minutes a slow process.
On massive battle between 6 fully fledged players would rack up points faster than rushing a base for a quick win.
It’s a strategy series. Takes time and planning for a reason.
