I don't understand the purpose of this post. You don't enjoy having to be strategic, you don't enjoy building relationships with party members, and you can't be bothered to either learn the mechanics or adjust the options to make things smoother. You haven't mentioned any shortcomings or provided any real feedback for the developers outside of "I like action games and don't typically enjoy RPGs." You just named a bunch of things that you don't like that aren't criticisms of anything specific in the game. That's not feedback, that's just treating a suggestion forum like a diary.
I just treat any post of this nature as a, 'these are the things I dislike, please explain where I might be going wrong.'
It is possible that it is, as you suggest, just a moan as one would put in a blog or diary, but I don't know why someone would go to the trouble of creating an account on a forum just to list things they dislike, especially if they are also saying that they are leaving. There must surely be a constructive point behind it.
