In FF14, the casual content is stuff that in many cases needs to be regularly done by savage raiders, probably more than the casual players. Roulettes for tomes. ARs for upgrade tokens. Even normal raids are useful for midcore raiders who might not be able to get the tomestone very quickly and getting 7 weeks of clears for a quick weapon upgrade is very beneficial. To say nothing of the most dedicated players being the most likely to level everything and thus spend the most time in the content. It absolutely is an issue for the normal content in the game to be too easy, which it has been for years. It has driven a few people I personally know who aren't even raiders away from the game.
If normal raids are the hardest content you will ever approach in the game, why wouldn't you want them to last you for a while? If you only want the rewards, or want to see a side story sooner, and you don't want to put in the effort to pass what is not hard, just non-trivial difficulty content, how is that not entitlement? I don't yell at SE when a savage raid doesn't roll over and die for me, because I do that optional content for that experience. I don't yell at SE when ultimates take a long time to prog, because I do that optional content for that experience. I don't yell at SE when I get awful luck on the extreme mounts and also can't clear them on the first pull, because I do the content for that experience. So why would I listen to people yelling for SE to make the midcore content designed to be non-trivial fights to challenge midcore players when they are experiencing exactly what the content is meant to be? If you want to do them, improve, or accept it'll take a while to clear them. If you just want the story, and not the combat experience, watch a streamer of your choice.
Plus you already have a ton of somehow even easier content than normal raids. The non savage raiders who want something with some bite to it deserve to have content too.
