I don't care what you think you mean; you are clearly on the war path and blaming [bold]your[/bold] problems on other players. Not only is it unlikely that Angry Birds players are playing FFXIV, it's near inconceivable that they are the ones driving the direction of the game. FFXIV's devs are following the massively successful WoW model, and it seems to be working. If you have a problem with that, address it. Complaining that filthy casuals are ruining your game is the best way to end up on the ignore list.
Or, you know, you could cancel your subscription and go play something else where you won't be bothered by casuals.
