If you don't like the mechanic; don't use it. if it's removed I'll mod it back in. that's how much i like this feature.
They are called potions, not vapors or some such, which implies they are supposed to be imbibed. Sure, it is feasible that there are droughts to each potion, which would then allow more than one character to use them, but if so, potions wouldn’t disappear after one usage. Also, each character would have to spend a bonus action to get the effects instead of one character using a potion like an AoE spell. Most importantly, though, if enemies are not programmed to use this “mechanic” then we shouldn’t be allowed to use it either.
Yes, you can mod it in at some point. You can also mod in whatever other exploit you wish. Have fun.
