Fun is a massive, and perhaps the most difficult, part of job design. Agreed, it definitely is not objective. No, missing a positional through no fault of my own is not the main thing that makes me find positionals not fun, but it is the main thing that annoys me about them. I otherwise am simply not interested in them - I did explain this. You said you skimmed, though, so I understand if this was lost as you read.
I appreciate you replying about cast bars vs. positionals and iterating again on the subject, but I already went into the detail of why they feel different (which I think you somewhat agree with). I already agreed that they have comparable merit on interruption/difficulty alone in previous posts, but their gameplay feel is decidedly different and that's the only bit that would be relevant to my feelings on positionals. I'm also aware of fight knowledge and iterating minor improvements on a fight as you get to know it, though I thank you for trying to inform me.
The only thing I "disagree" with here is the fun factor of positionals. I don't find this process fun, and as I've said before, it's not about the challenge or anything - I just don't. Conversely, I do find cast bars fun in these situations.
(the remainder of my post is not aimed at you in particular)
My post was subjective and there was never any changing that. Some people replied to me, I can only assume because they don't like that my opinion differs, and tried to make what I said about something it wasn't (difficulty). Examples were used that were decidedly not about liking or not liking a mechanic, and I pointed out why the example isn't about liking or not liking a mechanic and therefore doesn't apply to me. If they had made those arguments standalone and not utilized my posts to do so, I never would have had a reason to reply.
The entire point of me sharing that positionals are not fun for me in this thread is not to be contentious. When a mechanic change is being protested on the official forum, I think it's important for all preferences to be heard. Mine is just "hey, I like this change, it's fun for me." I love monk thematically, that does not mean I have to love positionals.
If the developers see that people don't find something fun, they could perhaps try to replace it with something else in the future. That something else, too, could posit challenge.
Edit: changed some stuff for clarity.
