Kaho?

[Randomninja]

Because for the longest time it was much easier and much cheaper to just buy it with Ads.

Plus the ingredients were ridiculous (aka the cards)

edit: just realized that spoilers say "Spoiler for Hiden" lol

Yeah it made sense to remove it back then when it was cheaper to buy from other players (or buy ads from others). But I'm confused why the GM said it won't be added back anytime soon.
It would be quite easy to fix any ingredient problems and now that kahos sell for 110m in the game I can see why some would like to make one instead even if it still needed the same ingredients.

They would still make money regardless because the amount of people who would just buy cards and ingre. Then you would also have those crazy rich people creating enough to overflow/over upgrade kahos. But if that was the problem we wouldn't have as many over upgraded sqi's as we currently do.
