It's called Spacebar

Did you ever heard about "delay"? And they will be rare so no you can't spam them like mines. A player saving the new supplies for months wont spend them all in the same single match.. just think about it.

500 Fps max settings 20% GPU usage Gang ?

Ok, but MM is made to be fast battles and you are not able to custom MM battles in any other games too. Just imagine for devs if they have to recreate stars increase/re-distribution battles, rewards etc it would be another pain for nothing. For most peoples 10mins is a good average for battles that's why they keep changing between 7/9/12 & 15mins battles to see which one is the most optimized for every player.

But what if i want to play JGR mode but doesn't have one hour to spent and only 15mins? A game mode shouldn't be determined by its time and the biggest problems of long maps are peoples leaving and then you're just finishing your battle with few ennemies.

Did you know that not everyone has your time lol? Think about others sometime. A lot of players actually just want to play a map for like 10-15mins and you want to make it from 20mins to 1hour in the same battle with the same players.. No it will get very boring it's not World Of Tanks here MM battles shouldn't be longer than 12mins each

I mean.. why not?
