Regarding the argument of healer vs tank damage:

If the displayed damage gap between healer and tank in other games is 30-40% but their healers also operate under the principle of expected damage loss due to spending actions on healing instead of damage, that would logically put them much closer in damage output than people think.

If let's say a healer in another game has the opportunity to spend 95% of their actions on their damage spells, that would probably put them much closer to the tank in terms of output.

Meanwhile, healers in XIV just arbitrarily do less damage than tanks for no discernible reason even though they both use a large majority of their GCDs on damage and most of their role responsibilities are done through damage-neutral means.

Most people try and argue that tanks do more damage because they have to keep aggro, but that's a weak reasoning because they could very easily just boost tank stance aggro generation by 20% after reducing damage output by 20% (example).

It's important to note that doing damage isn't stated to be the main role of either healers or tanks, so why do tanks just get special treatment with a fleshed out damage rotation and higher output?
