If the OP didnt blow them out of the sky after the first merge EVERYTIME maybe they would hang around more than 3 flights.
Obviously you're unsure who you're merging with until the first pass. I was exagerating the typical experience. Some MPA players are purely out for score and will just take a set of duels with a noob as a gift.
I always try to help, usually they don't respond at all, I think they haven't even figured out comms yet.
a vet knowing a players is a newbie could be come a great ambassador for the game by slowing down, giving the newb your six and letting them get off a few shots. A few wins and that start getting hooked, a few more and they start learning and before you know it they asking questions and taking their lumps like the rest of us did.
I've do this a lot, even posted about doing it a few months ago. At least two new players from other flight sims I've spent an hour with each. Unfortunately not been back either.
I'm getting a general if-you-can't-stand-the-heat theme emerging here. While I agree to some extent I think the MPA is a bit Chinese restaurant gas-burner level of heat. Frankly, haven't seen a lot of those posting in the MPA either

Insofar as the non US primetime I'm just reporting my experiences as first contact for a lot of players. Perhaps the can't-stand-the-heat thing is not very fashionable these days. The danger to conservative approaches is when the environment changes. You end up with one chef cooking for himself in what was once a busy restaurant.
