Just had my 4th win this morning using only the ping system. I had a pretty good round as Lifeline with a couple of kills but the MVP of the squad was a Wraith player with a Mastiff and 10 kills!
My favorite part is that our 3rd squad member was Bangalore and they seemed to be new to the game. After a few firefights they went down. I was able to recover the banner and made a risky dash to a respawn point and managed to get them back in the game and they stayed alive through to the end. It is the first time in a game like this that I feel like I maybe helped someone get their first win and it felt awesome!
