Without a full spectrum of tactical mission possibilities and strategic goals, with a VARIETY of rides to play in, yes.....any Korea Dogfight arena consisting of a Mig15vrsF86 plane set would simply be a novelty. 98% of the player base would play there for two weeks then get bored and go back to the far more dynamic LW arena.
This is the lesson WW1 has taught us: One, maybe two planes with a pure goal of nothing but dog fighting, no matter how well done, will become boring to the majority of players after several weeks or a month.
I hope HTC puts more effort into developing WW1 into something more engaging over the long term. the SE5a and Albatross, SPAD, Nieuport 17 just to name a few, with some large bombers and other strat elements would go a LONG ways towards making WW1 a FAR more viable arena then it is now.
