Earn: "to gain or get in return for one's labor or service: to earn one's living" So, in my opinion, it doesn't matter HOW someone completes the Raid or the Nightfall or whatever, all that matters is that they've successfully completed the task. You choose to kill the lion with rocks and sticks; they choose to shoot the lion in the forehead with an AK-47. The lion still dies either way. It's a matter of opinion.
