Savage and Ultimate has consistently getting harder, so I don't see where this LCD claim coming from. You're just projecting because you want the "easy" content to become harder to carter your taste. The game clearly draw 2 circles for people to stand in, and everyone is free to visit the others, but you don't get to make the other territory yours.
Class and system streamlining is unfortunately are always part of the growing pain for any game that stay around too long and get too big. Name me one main stream game that have been around a long time and is exception to this, I'm all ears. So this particular complain certainly is valid, but also it is like complain about why we don't look as good as we getting old.
This is one of the reason that no matter how much I like FF14 I don't wish for it to go on forever. Eventually the game will buckle under its own weight and all resource will simply have to go into maintenance instead of creating something news. I would much prefer we hit a reset point with a completely new MMO from SE eventually.
I admit, I had far more trouble in those early 2.0 trials than I do in the modern now. But I bet it had more to do with circumstance rather than the actual difficulties:
- The game was relative new, and everyone was equally no0bs. Titan was hard for me because I misunderstood how attack was telegraphed in FF14, which was almost the complete opposite how it was in WoW. Case in point, how often you see a sprout struggle and failing a mechanic that you can do with your eye closed? Me, all the time. Also during my down time I'm a MMO tourist who also try out other games. My experience in doing savage/ultimate often means squat, and I would fail simple mechanic that the veterans of those games think "easy".
- There weren't a lot of seasoned veteran to carry a failing group. You come in and you have to pull your weight, there is no "doritos" to follow that will get you to the end of the fight even if you don't understand the mechanic.
It's not a question of the player skill, it's about the institution knowledge you accumulate. This is what people who so good at this game and demand the "casual" content to be harder don't understand. As the veteran with that ingrained knowledge about the game, to make the casual content challenge enough to entertain them would also make said content pretty much prohibitively difficult for its actual intended audiences.
