As far as i know, in FCOB, i spend like 80% of the fight targeting the same boss and during this 80% timespan i'm prolly using a maximum of 10 actions.

Dodging with an analogic stick is extremely easy. With a 2.5s GCD that's plenty of time to switch crossbars. FF14 isnt Shootmania Storm.

Now if you want to remain the only special snowflake who is the only person running coil and still believing that KBM is mandatory well its up to you but
be prepared to look like a bad player regardless of your titles / achievment / look / whatever. Attitude makes you interesting, not the shinys.

On a footnote: we are in April 2015. Betting that a random player "dont even final coil" like you did for me, without any proof prolly worked back in Nov 2014 maybe but now it's a risky bet.*
You don't know me. Keep your shitty assumptions for yourself.
Almost everybody is on final coil. Just wake up.
