I dunno, having a single dose of poison being viable for multiple attacks is quite a good discovery, even at 1/4lvls discoveries. Mainly it's due to the new pathfinder poison and disease mechanics though, and better poisons being available.
That's true, but with the ability he made there would be less actual poison buying. And if you level base the discoveries instead of making them so that you have to have a certain number of other discoveries, then being able to use a poison more then once will be fair, considering that the saves of the enemies goes up in the high levels that discovery would need.
