As always with modern design of jobs in FFXIV, an additional crux is that there is absolutely no reason for something like Autocrossbow or Scattergun to even exist. FFXIV employs no mezz-style CC (and to that end, no meaningful CC at all), so there is no reason to have separate AoE skills. Every single-target skill could instead be "Deals X damage to target + Y% less to surrounding targets", and all AoEs skills could be removed to clean up the hotbar at exactly 0 loss of gameplay. And as a side-benefit, this would fix many of the issues of the current AoE gameplay of Machinist.
