Back in the ARR days, I loved playing Dragoon when I wanted to go burst melee on my enemies. It was fun, I knew the rotation and could deal DPS with the best of the lot.

Now in Heavensward and the job at 60, I avoid it like the plague. The addition of the 4th tier combo, to me, disrupts the flow of the job too much. The skill bloat does little to help its case.
Sure, the rotation makes sense and the DPS is phenomenal on single targets, but it feels so forced when its time to do Wheeling Thrust or Fand and Claw. The loss of that much DPS on positional RNG is rather large too.

It might be my personal opinion but I just don't like the 4th combo at all.
