I don't get it, we already have Ultimate acceleration vials in donor shop, which includes 6 vials per round, most TDM rounds will last anywhere between 1-2 minutes, be efficient enough and you'll easily make it last until the next round. Which you have also agreed on:
If by "competitive tdm" you mean any normal TDM then I doubt it would be any more disruptive than the normal speed vials are already, which they're not. What is it, like 3 vials or 5? It's basically enough already to last you an entire tdm round.
I don't really see the demand in this either, it'll just get forgotten after a few days of release.
