The lack of 'classic MMO grinds' is the exact reason I play this game and remain subscribed to it continually while anytime I try to play WoW it is a flash in the pan for me. You finish it, it's fun, and they go "Alright buddy, here's the mountain you have to climb to do anything else!" and it's an IMMEDIATE turn off because I have a life, a job, and I can't sit and farm crap and do 6 hours of dailies per day just to keep meaningfully and reasonably current. Grinds exist for sub retention, not fun, and is that what we really are looking for? More people doing grinds they hate?
I want them to break away from the formula but through things that are actually fun and engaging, not brainless grinds. This is why OC is really flopping for me pretty hard, which was making the last step of it something for hardcore grinders only is incredibly meh. Sitting there going through and grinding with the understanding that, due to life I'm just never going to see, let alone complete, Forked Tower is extremely meh. It was a massive kick in the groin because field content was always supposed to be 'for everyone', and locking that away behind more content for raiders was a VERY bad decision.
I'm holding judgement on the final boss of the new DD because we don't know what that will look like yet, but this trying to 'hybridize' things to draw people into 'harder content' to justify the amount of time they are spending on it just needs to stop. I mean YoshiP, I am not doing Savage content not because I don't want to, I am not doing Savage content because it is designed in such a way that 8 people need to make a 3-4 hour commitment 3 nights a week wiping to the same absurdly complex mechanics over and over until they figure out the silly 'ballet' that has been designed for each fight.
And Dynamis and Materia aren't going anywhere because the game's housing system pretty much precludes the concept of server merges.
