I've been playing off and on for about 6 years now. But I didn't meet my wingman Gravedigger until last year. I'm glad you liked the Vid! We've been a bit busy lately, so we haven't played in a while, but we hope to make more videos soon!
Very debatable. I don't think its the worst thing you can do though. There are definitely worse choices out there. I usually recommend researching the playstyle of a premium vehicle before purchasing and definitely playtesting it beforehand. Also, it depends on what you're trying to do because I learned how to play top tier jets by getting a premium high tier jet so that I would have more experience when I get more planes in that tier and not get as discouraged. So, it kinda just depends on what you want to do.
Oh dang, that's a tough question, just because there's so many lol. As far as looks go, the Harriers have always been my favorite with the big engine fan right behind the cockpit. As far as my favorite plane to fly, I put in a lot of hours in my Sea Vixen F.A.W. Mk. 2. It was my first premium jet, I got a long time ago, but it's still one of my favorites to fly.
