Having synergies isn't damning; it just means you have to balance comps, not only individual jobs.
It just comes back to whether players actually want XIV to be a team game beyond merely picking an angle, and perhaps an 'out' or 'in' position if there are more ranged than melee, before performing their mostly unchanged T&S dance. So far, that seems a no. We seemingly like as little effect from playing with others as possible, or indeed of any chance, anything outside our control.
