Carrie's response from the Dev Q&A a few months ago:
"[CVG] The technical answer is that handling a massive number of drops is not currently supported in the game. That said, it would be possible (with work) to enable that. We have been talking about what to do with the Bronzium packs and system overall, and haven't yet landed on where we think this aspect of the game should go yet. All that currency was introduced with the tournament system and was intended to be used for that. We weren't prepared for it to be used only for bronzium packs, so it will be more challenging than simply enabling that functionality"
