I am confused..Auto attack?

[Preypacer]

When's the last time you played XI?

I highly doubt you are attacking this fast:

I bet even the whm here is attacking faster than the fastest DD in XIV.

That video is sped up. The music is faster, the attack sounds are faster and slightly higher pitched, the animations are faster...

Not a good example.

And anyway, we don't know all of what gear those players are using (least I can't make it all out, vid's kinda dark). At the least, both characters are wearing a Walahra Turban which by itself gives 5% haste.
