I just want to point something out that I see missing from most "how can we make stuff less boring" posts (a charitable version of the "healers and tanks need to dps or gtfo"): there are a lot of people for whom my "boring" is their "hectic". I get that a lot of people find the mechanics, once learned, to be monotonous, and I can't blame you. And I don't see a reason not to shake things up for the higher-end content. But "shaking it up" (making it more intense/harder to predict/etc) in casual content (i.e. DF dungeons) would be a deathknell for the game for quite a few people. I have friends for whom duty finder is the highest they can handle. And before people spout "lazy" and "get gud", understand that a lot of these people can't. You look at "that healer is only healing omg" and think "they're laughing with their FC or chatting in an LS or playing a mobile game" but the reality, for some people, is quite different. Some folks have anxiety so badly that just getting through the MSQ dungeons is a test for them, but it's nice that they still have "something hard" to work on that will eventually allow them to get some of the end-game rewards. I know one individual who suffers from hand shakes (I think it's tied to a syndrome or seizures but I don't ask) to the point that they have to use a special mouse. They can't do Omega normal. They can't do Rabanastre. But they can run a 70 dungeon once a day and get a feeling of accomplishment.
I don't think that pointing out ways that the game can be improved is a bad thing. I'm sure that what we have can be refined so that it's better for everybody. There are probably design choices that, when changed or removed, would make the game better on all fronts.
But please understand that casual content is casual for a reason, and not everybody who isn't performing to your standards is "lazy". For some people, this is all they can do, and they enjoy it. Should they be trying to change high-end/hardcore stuff to make it accessible to them? No. But neither does that mean that their casual content needs to be ramped up to the levels that a high-end/hardcore player wants.
And if your response is just "get off my game, then" or "find another game," please remember that this game was designed so that they have content that they can handle. They did find a game that would enable them to play at their own pace.
