The way to survive in a P47 is to always stay above 300 IAS. If you're above that, you won't have no problems maneuvering.
Tough to maintain 300 IAS if you're maneuvering for a shot against a Spit, N1K2, Yak, etc. If you sell out, the P-47 can work around onto almost any plane's 6 o'clock. The only problem is that once you saw his wing off, you're a complete target, and will stay that way. My squad originally started using hard decks some time ago, but as everyone would merely dive away from us, we had to change tactics. IMO, the best way to survive in the MA is for you to go in with wingman. If you have a 4 ship, let 2 go in and mix it up, with 2 staying above for cover. If you have a two-ship, keep one up and one down.
Picking your battles is another problem. If you're outnumbered, but with altitude, all you can hope for is to knife through the blob at high speed and pick up the "low-hanging fruit". If you try to isolate a single target, you may kill him, but ultimately, its a Phyrric victory, as you'll be pounced. 1v1 or 2v2, have at it.
Jug is my favorite aircraft, but can be a pain to fly in the MA. It'd be like being an LA-7 fan if everybody wanted to fight at 25,000 feet...
