An enlightened viewpoint, and one I must confess to sharing. And sharing is appropriate, because that's one of the greatest pleasures you can have. Taking the time to learn to dance with Titan has been one of my greatest moments so far, seeing the performance of myself and my group improve until that perfect run, with the Free Company all moving in synchronicity, anticipating, adapting, coming so close to the win many times then the final golden moment where the screen goes black and the feeling that all that rehearsal and preparation has been rewarded. If you ever need someone to help out with a dance, Moon Flow, feel free to ask me, and if I don't have prior engagements I'll always be willing
To the OP: I would infer from your list that you believe spamming dungeons over and over is the only thing which you can do to improve your character and prepare to start Endgame, and as a fellow Monk, can only assume you are coming here looking for suggestions to help open your 7th Chakra a little wider.
- Help others. Offer to do things for people in your FC even if you don't directly benefit. People will remember and repay your kindness.
- Instead of making gil to buy your way through difficult content, spend that gil to investing in your character until you are able to beat the content yourself. Work on your strength stat, set yourself a target and go for it!
- Do the items in your list of "endgame", but vary it up alot. Don't just log in and spam AK 8 times, mix it up, take your time over the course of the week, help people who need primal fights or weapons and get some of your tokens that way too.
- Level your subs. Check out which abilities cross class from other jobs and go out and get them (I'm currently aiming to get LNC to 34 to acquire Blood for Blood for my Monk). Of course, you say, "one should suffice"... it does, but only if you aren't aiming to be the best Monk you can be.
