Positionals are fine for some added skill gap with melee classes. However, after leveling Monk, I do feel that job goes a bit overboard compared to the others. Especially with the attack speed they have, having to constantly move back and forth while dealing with problem tanks who can't keep the boss still or enemy mechanics that turn the mob can be an exercise in frustration. Samurai and Ninja have two positionals. Dragoon will have just three after expac hits. Monk has SIX.
