SGA: the best way to earn points for your team in the Iron Banner Clash
Just don't die.
You may be a bad shooter (I am). Still, just don't die. Every time you die, you give points to the opposing team. So, it doesn't matter if you killed an enemy, or just saved your life. BTW, The Ram helps a lot.
PS Is the scoring table for the Clash mode reasonable? That guy with the most points didn't help much our team, it seems, with him dying so much.
