Wow, whole swag of issues here, just want to comment on a couple.
1) Yep, the re-arm pad is gamey, but as Joc points out, so is the whole MA. But even within the parameters of the MA game, the fact you can still re-arm when a field is to all intents and purposes dead, has always seemed odd to me.
2) Repairs. I like this idea, since it does give you something else to do with your perks beside fly around with a big "Roger me roughly" sign on you. I don't think it would have to be a map of your plane of anything like that. You pull up on to the re-arm pad, a smoking near wreck, and the system simply asks you if you want to repair your damage, and tells you how many perks it will cost you (more for an engine than an aileron, etc.). You say yes or no, and you're on your way.
3) Sorties. That said, I actually don't mind the idea of the sortie being scored as one up and down. However if this were introduced, it would, I think, need to be coupled with some means of kill streak tracking across sorties. You wouldn't have to keep re-arming and inflating at the moment if you could land with 3, and no that when you next upped you'd start working on 4.
4) RPS. Both Joc and I played this in Warbirds, as have many others here, and although I didn't find that it made any difference to my enjoyment, there are obviously a lot of people who don't like it. And it's sure driven a lot of people away from Warbirds (in combination with a lot of other things, obviously--feeling a little sad because I finally cancelled my token subscription to IEN yesterday--gave them 6 months of donations and in that whole time saw only a couple of minor changes). Before we can even consider a RPS we need a lot more planes: all nations, in all phases of the war, need to have multiple options available, which will increase the likelihood that people will get to fly something they like. And the RPS period needs to be longer--the one month period in Warbirds was too short, because it meant that the rides people were looking forward to were only available for a couple of days. Maybe 2 months? But anyway, we're not in a position to be able realistically talk about an RPS yet.
