Rumble keep it 1st place win
Rumble 2nd place also counts also wins
Rumble 3rd place also counts as wins
As a PvE player, I know the pain. I'm not even going to attempt Rumble wins. Though as a long time Trophy hunter, I'll say simply, if you can't get it, you don't deserve it. Too often in the Playstation Trophy scene, you'll get people complaining about trophies being difficult or exclusive and they'd draft 'petitions' to have them changed, but every time, it's just a matter of 'if you can't get it, you don't deserve it' That's all there is to it really.
