Sounds about right. I think that previously, the average drop on R weapons from 1000 pulls was about 80.
And yes, you'll recoup less thanks to selling the stuff but... think positively! Less Ns means LESS time spent watching that stupid "Connecting..." in the Mass Sell menu after the first batch. Also, recouping less doesn't really matter since Gems are now an infinite resource. Hell, my "break point of 84 AP for infinite Gems" math didn't even include selling anything back...The jargon that these forums generally use is AB and AAB, I believe.
AB = Auto Battle (no skills)
AAB = Auto Ability Battle (with skills)
