I also doubt that while in the heat of action with your hand on some other hotkey you'll be able to move it to the firefield, target the location he stood on, and cast it within 0.5 secs. That's not a long time, so if that's the time u have to do it then I think it could be hard. But like Gang said it's easy to test, I mean even if you don't get invis by taking damage yet the recall should still fizzle, so it's easy to find out.

I think Lags idea is the best, having a macro to magic arrow your potion in your backpack is easy to setup both in injection and razor, and if u see somebody drinking an invis pot u could actually pull off hitting that hotkey. If it's IMPOSSIBLE then I'd recommend making recall scroll time longer.

And about Depths suggestion with the "invis reveal potion".. well that could work as well but I think the magic arrow on explosion pot is a better way, and you'll always be able to do that, even after drinking another potion giving you a timer. Plus I don't like the fact that it will be instant, I think the time it takes to cast a magic arrow is about the time the guy deserves who bought an expensive invis pot, and like I said, if it's still too hard to pull it off then we could always make recall scroll time longer.
