Quoted from Larcx @ Aigis wikia (who in turn obtained this from ULMF)
and yes, you ARE sacrificing unit exp, but you will eventually get a point where unit exp isn't the world to you.About Betty
Found this on ULMF
Let's assume you have 480 Charisma. Using 5 SC will result in 6 times this amount (480 regen in 24 hours) which is equal to 240 runs of Pastoral Gate. Farming it with awakened Betty will give about 3600 G per run. This leads to 432 Summons a day. I am assuming the chance to get a unit of a rarity above X is 0.01 % per pull (actually I don't know the real values, this is just a proof of concept). Therefore not getting any unit at a rarity above X is 0.9999^432 = 0.9577. Or in other words: The chance to get at least one unit of rarity X or above is 4.23 %.
So with 5 SC a day , You could do 432 Normal 2K Summon
And yeah , IDK how Lv of Prince to get that 480 Charisma
But that seems delicious to get 400+ Summon a day
Everyone has his own point of view anyway
But , I think Betty worth it to get AW~
edit: and I might as well point out that this IS a viable method, just tedious. and that you need to run Pastoral Gate manually, not commission sortie. and 5 SC = 1 premium summon, but you're pretty much guaranteed to get more than 1 silver out of it.
edit2: based on other people's research results, Mysterious Beast (20 charisma, 92 units to kill) is potentially another good place to farm gold using AW betty/Lyla.
Nonetheless, for those players with AW betty, remember to use her for Low Cost Battle 1 when farming it, since you probably have to anyway for silver fairies to CC silvers to be used as AW fodder. Enough silver fairy farming through LCB1 also allows you to use those silver fairies to combine with Hashim and other higher level bronze units (2 silver fairy, 2 bronze units) for fast silver unit leveling (to 30 for CC'ing)
