I must say, I'm actually tempted with the current offer, to get 2 more equipment slots for Acacia, and to unlock the second equipmentslot for one of several girls with personal jewelry.

That is indeed true, but If I recall correctly HH could still use a couple more Rainbows to pad out his teams power.
For someone like smr or Ivanleadh who run full 20 rainbow armies, those dressblooms have more value, but for people who still could use more power, those new 6* girls will prove a solid option.
This will be even more true once we get the Whaleship missions... August was the date for the update IRC someone mentioning it ?

But yeah as I mentioned before - waiting for the 6*+Dressbloom gacha would be the best choice.
