Absolutely agree to op. The impact on the economy is not a valid argument for not implementing a bronzium multi pull. The only thing it changes is: players dont't feel like test animals when they have to press the "skip animation" and "buy another" button repetetively.
Maybe that's because I'm playing this game from the beginning, but I don't have a lack of omegas. I do have a lack of gear, so the extra shards from the bronzium pulls are much more needed than half an omega ability upgrade.
