The buff is incredibly minor, especially compared to other buffs that were given (not that monk needed damage, and if anything I'd have rather seen the buff on Elixir Field so its potency matched Rising Phoenix, it really needs the rest of the garbage in its toolkit addressed... but monk has always been the king of useless buttons)

But like Aeliott said, no. This doesn't make it better to use phantom rush as soon as you possibly can, because at 60 seconds in the only possible boosts to the attack that exist would be riddle of fire and trick attack. It's even more important now to hold it off till the 2 minute mark than it was before.
