Hell it doesn't even have to be raids. They could add new PvP modes with actually useful gear you could work towards. They could fix the crafting system and actually let it be apart of endgame gearing. I had all crafting classes maxxed out and geared in 2.x-I have a grand total of 2 and haven't bothered to even do red scrips cause they suck.
Some more raids that are worth my time would be nice too however.
Oh, I agree with this. There are two problems preventing this and hopefully they get them resolved.
First is a problem of attitude. Historically the Devs have actively opposed crafted gear bring relevant to raiding, and PVP gear isn't even really useful for PVP, let alone raiding. Supposedly in 3.2 they'll be introducing crafted gear that is about on par with raid gear though, so hopefully that attitude is changing.
Second problem has been that as the game has gone on, thier development has become less focused. In 2.0 and 2.1, the game was all trials and raids, with a bare bones PVP mode on the side. As of 3.1 its, raids, trials, pvp modes, diadem, triple triad, lords of Verminion, and that's on top of all the old content that they're always adjusting.
I'm all for experimentation, but it doesn't really feel like any portion of the game is really getting the attention it deserves right now. With this in mind it's hard to see how they're going to go into certain areas and overhaul them to make them more comprehensive.
The only way I really see around this, is to focus development a bit more. For example, as novel as Verminion is, it could have been put on back burner development until they had enough content ready for a more comprehensive Gold Saucer update, and it wouldn't really have hurt 3.1 any. Heck, with those resources freed up they might have been able to polish up Diadem a bit more, or added a new Frontlines ruleset, or something. As is, they probably gave up a bit of content elsewhere for the sake of having a mini game that appearently needs a bit more polish.
Edit: To be fair, if they get the new raid in 3.2 right and people actually like it, that could go a long way towards fixing things.
