The point you are missing is, this gacha of Cactus 6* it was like Kerria 6* same spend and same benefits, there was a BONUS if you wanted of Cactus Bride, the keyword is IF, if you didn't want to spend on her that much you just wait for it in the 16th event and no big deal, you all doing to much blah blah blah and drowning in a glass of water. The event was made for Cactus 6* and as a bonus YOU COULD buy cactus bride if to expensive for anyone then just wait till they hit the gacha when all the brides arrives. So besides the bonus what difference was this guaranteed of cactus 6* than Kerria's?.
Besides people collecting 6*s by guaranteeds they spend on it because Cactus was not as regular seen as any other like FLower Peach and BB and those other 6*s and people still vote for them, so why dont you go yell at them in favor for the tons of people that actually own those 2 girls?
that what benefits would they get if they alrdy have them and so on??. Is simply people that we got Flower peach and BB we just simply pass in the gacha and don't go yell or cry about it.

Lets take here your example.. its 39.99/month for internet you say.... Lets suppose you dont want the Phone Lines but YOu do want Internet and Cable. So theres a package of 39.99$ for the 3 things, and separated the 2 you want are 45$ so what do you pick? Knowing you should pick the 45$ since you dont FKING Need the phone lines and since you don't need them you rather pay more. Then later when the package expires and you need a Phone line lets say you want it and you have to pay more? or wait for another package maybe not as excellent at first 1?
Is as simple as that some rather buy her like that now and dont fking waste gems to try to roll her later no big deal.
