At the start of the game disconnected/resigned teammates

today , 3 times in a row, I lost ELO because of disconnected/resigned team mates. I play 4v4, 2 times at start my team mate disconnected and ofc others quickly left, and once at start 1 team mate resigned(i mean what the f** if you had to do something cancel or alt+f4 before loading screen ) .
In total i lost -45 ELO , and i think it isnt fair.Im not someone who “cheats”( plugging its internet cable or smth to dont lose ELO) ,however I dont want to lose ELO for this reason because in team rating,imo it is harder to gain ELO than normal rating since you may lose because of your team mates even though you play at epic level.

My suggestion for this problem is, if someone leaves/disconnects in first 1-2 mins , there shouldnt be any ELO change for both teams. There might be some people who abuse this, but if you compare numbers, people who stricken about this > who abuse
