I think I'm misunderstood when I said this game lost it's 'distict identity'. Let me clarify and my apology in advance, it's going to be long winded.
1. Lore
Originally this game has its own history and lore seperated from other Final Fantasy games while we do get recuring themes like magicteck, primal, etc, the idea of mixing Final Fanatsy 12 world with this game never occured to me as possible before it actually happened.
I do like FF12 but FF12 is FF12, it has its own unique history world and characters but now we got it in the form of actuall place that axist within FF14 world. We now have Viera and Rhothgar from FF12 and FF10 respectively. It was done because the fan wants it.
Soon we will get Nier world incorperate into this game lore as well, while it is cool to the fan to see their other favourite game appearing in this game, it dimishing this game identity. How far is Yoshida willing to give into the fan for these fan services? Are we going to see Kingdom Heart and God forbid The Avengers in this game in the future too?
2. World
The world ofFF14 in Real Reborn was rich and a joy to explore, small as it was it was packed with rich details in the environment, it sold me the idea that this world is a living breathing place. When Heavensward came out they introduce flight which in itself a cool exciting idea but the unintended consequence of that was a large empty world, even the city hubs are scaled to such a size that my hume character feels like an ant. The hubs itself haven't got any denser, it just scaled larger. I mean have you seen how big those lamp post are in Lakeland?
The size of the enmeies, over world and in dungeons, are scaled to rediculous size to keep it inline with the size of the world. Do you remember Vishap from The Steps of Faith? It was the largest enemy (discounting Bahamut) we encountered but if we go back there now it would feels like he's just a little bigger than your normal everyday mobs on the world map and regular dungeons.
3. Class/Job
Being an MMO I can see why the devs have a great challenge ahead of them to keep all jobs ballance, this however come at the price of the jobs identity. I remember in Realm Reborn, despite people opinion on its viability, Paladin and Warrior feel very distict from eachother now we have 4 tanks that play almost the same as eachother (Gunbreaker felt more unique IMO). Bard should have been the de facto support job yet it lost that to become just another DPS. Healers got.... lets not even get into that......
It's not hard core contents that I'm asking for but the quality of the game as a whole, right now it feels like we have too much to do but all are the same things with different dressing. The engine that they use itself is getting quite old, if they are trying to push for more pretty graphic then I think it is easier albeit more expensive to just switch to a new engine, one that specifically build with the game in mind.
Ultimately I don't think it will happen though, from business point of view, this game still stand to make a lot more money for years to come yet. What will likely happen is player like me will get tired of it eventually and leave but there's not enough of us to make any impact that would persuade them to make another MMO under the Final Fantasy banner.
