Hmmm.. EXT floor boss gives an average 2000 per fight (3000 passes from rune boss) during rune time.. so  if you don't lose a fight,   10 bp = approx 20k floor passes..

Also, compared to last tower, which provide a card with a not really necessary skill (since you can get that skill from custom skills), most players prolly saved their crystals then and choose to spend on this tower event.
