DNC doesn't need damage, it needs utility and support.

Contradance should cost finishing moves(tier 1, so ~30 second cooldown)

Fan dance should reduce damage done, lower waltz timer, increase waltz potency, etc.

Saber dance should give something relevant, it's double attack is incredibly weak at this stage of the game. I'd rather it buff support somehow, DNC doesn't need more damage.

Haste samba absolutely >>NEEDS<< to give 15% for a DNC main. Haste2 + MG caps haste, haste2 + 1 march(any) caps haste, but haste samba + haste2 is not enough to cap delay for basically anyone.

Frailty should be nerfed to the ground(geo is 0% interactive/fun in melee set ups anyways - make it a mage set up buffer only please)
