Agree. Though I can't beat the Extreme Rune Boss (not if RNG isn't at its peak) so I only do Advanced but still, with a chance time climbing ranks is also fairly "easy" in Advanced. Though I simply hate the 45 min wait... When it was 15 min it was nice cuz then you could perhaps use the last BP in a round battle and then encounter a Boss (20 min time limit). If BP recovered within 15 min you could take out the Rune Boss as well during those 5 extra min but not anymore which sucks... -.- Have already used almost all of the free crystals... :/
