I assure you, any DRK worth his salt knows that the updated Last Resort when using 5/5 Desperate Blows basically removes the need for any other Haste-giving Job Ability, especially if you put some merits into the Last Resort Recast time, changing 2 minutes to 70 seconds.

It essentially removes the need for Hasso completely since the STR and ACC boosts from it aren't as important as the Haste it gave.
