Really, if you came into FFXIV expecting the game to be heavily PvP focused then you were always going to be horribly disappointed. FFXIV is, a FF game, and the FF series have never been about competitive multiplayer - spin-offs maybe, but the main series has never been about players fighting each other, even in FFXI PvP was never nothing more than a minor diversion completely separate from the main game. FFXIV is PvE not PvP focused, it always will be.
Also, that's the nature of game development for you - concepts and ideas might be mentioned and shown, but during the development process aspects planned may be discovered to be for whatever reason just not implementable to how they had mentioned it, and thus it's either altererd to 'make it work', or excised completely.
This isn't a terrible thing, it's a natural part of game design. Unfortunately players don't usually take this into account and thus it's far easier to articulate "They lied to us!" when a certain content idea is mentioned and then later on scrapped, than simply accepting this is what happens when developing a game, especially MMOs.
It's why early trailers for games after all usually carry a legal disclaimer along the lines of "The following shows this game in an early stage of development and thus may not match the final version," things can change at any time (it's also why developers are usually tight lipped about what exactly they're doing.).
As for the Cash Shop, players actually begged SE for it, so blame other players, not SE, they're after all only trying to please everyone. Really these sorts of posts they may as well not bother trying to because no matter what they do it's always wrong.
