The damage feels so low that I don't even notice when I press a GCD. The nerf feels especially bad before level 52, when Machinist unlocks Auto-Crossbow, since all the generated gauge can't be spent on a stronger AoE, forcing constant overcapping. So it feels even more like I haven't pressed anything.

The strangest part is that these two GCDs were nerfed because Machinist's AoE was expected to be too strong with the 7.2 buffs to decaying potencies. In the end, the opposite happened: Machinist ended up feeling like the weakest job in M6S, where you'd see 10 Dancer clears for every Machinist clear. The gap in add-phase damage was around 10%.
