Bard is deceptive. You would think it's the easiest job because you just spam 1 GCD. But it's actually the hardest ranged physical job, in my opinion.

Bard has to:
  • Apply DoTs and refresh them right before they expire, without getting distracted by mechanics.
  • Keep songs up and rotate them as each one expires, without fall off.
  • Resist the temptation to use Pitch Perfect until they have reached 3 Repertoire stacks so it has max potency, then spend so they don't overcap.
  • Try to use Apex Arrow near cap without overcapping.
Rest is just easy weave everything off cooldown.

In comparison an MCH just presses everything off cooldown and that's kinda it. The hardest part of MCH is accidently starting Hypercharge before using Drill/Air Anchor/Chain Saw, or overcapping Gauss Round and Ricochet, but compared to Bard it's just a ZzZz tank rotation.
