If P2 > P1, then they are better off investing in Legion.
If they invest X in a new game, they can earn P3% more profits, so that may even be better than Legion for them. A game like Hearthstone. But how is HS different than legacy servers? It has the promise of a future. Those devs who work on it will keep making content for years to come, and the money will flow. Legacy is a very contained project; maybe it will draw a "Wrath Baby" like yourself, because if you started in Wrath all your veteran friends were bringing it up to you. But it will not attract a fresh audience, an audience not already interested in WoW.
That's not to say legacy realms would NEVER be a good idea. Like I said several times, when WoW reaches the end of its life cycle, trying to widen your audience by providing them with more varied environments to try out or retire to, to remember their golden days. But that's not now.
I guess this is why so many people are against you: you want a feature that belongs in a dead game, in fact some of you, like Uurdz, actually want the game to die, while we still enjoy it a lot.
