And you want potions to last even longer than they do with BrewM from Arena? There are some that already last 16 hours WITHOUT any BrewM; we don't need things that extend the effectiveness of our "overpowered-ness."
Sinking more potions = good; making other potions last even longer = bad.
The game economy doesn't need even longer lasting Instant Teleport potions for seasonal titans and cows. The market is already flooded.
The idea behind extending our already lengthy potions is a ludicrous idea.
