M5S Clear – Dancer POV – Arcadion Savage – Patch 7.2 – PF Strats | FFXIV
Dancer is a dps role with only 5 DPS abilities. Just 5. Yet to keep uptime and do the mechanics required is still VERY tough. Not as tough as a caster, but still crazy hard.
It does not matter if you only have 3 buttons. Mechanics are mechanics. More buttons doe snot equal difficulty. I do not understand why Warcraft players feel otherwise.
