I dislike positional requirements too just in general when playing melee DPS, I have a MNK and a BRD and the MNK is extremely more complex to maximize DPS which is partially due to those annoying positional requirements. In fact I have given up caring about position on MNK but mostly because I hate playing it and only level capped it because I had a leftover PUG from 1.0 that figured might as well finish leveling.

I will care more about positioning if I enjoy playing Rogue/Ninja but I won't give a damn about position for the most part up until start doing EX primals and Raids when that positioning for squeezing out additional DPS is much more important. I would however be very happy if some day they removed positional skill requirements, I won't deny that.
