L2Math.
On 2v2 Map, with 50% map control you gain 26f per minute. At 15min you have (let's assume that you need 2 mins to get 50% map so at 15min you would have 13:30min fuel with 50% map income).
So 26x13,5 = 351 Fuel.
How much fuel you need to rush KT?
380 fuel.
Gap? 29fuel which is less than 1 drop form OST player.
Now you ve been completly outplayed by 50% mao control to get 15min KT (of even faster with 2 drops which would be 100/26= 3,8min, so 15min-3,8min=11,2min )
i won't do pointless math for a non-existing vacuum, i will play the game.
that's how you get better, you know
