So I've been playing a poisoner recently and I've run into a quite a few things that hurt the playability of them. The biggest of which is the fact that you have to brew the poison immediately before using it. There's no option to pull out a vial apply it and get to work, you have to have the ingredients brew it (20-30 second lag), apply it, and then you can use it. If I want to knock someone out they pretty much have to be staying for that entire time and whenever I've tryed it the opportunity has usually passed by the time I'm ready to take advantage of it. And you can just forget about making use of poison on the case that someones coming after you.

The second problem I have is that one of the most useful of poisons is almost impossible to use unless you cross train to plant and get very lucky. Emetic poison is the closest thing to normal poison and yet you can't use it like normal poison. I could understand this if this was an assassin or warrior we were talking about, but with thieves their hardly the most dangerous of classes (obviously yes they can be dangerous but compared to other classes not really). Also both mind control and knock out I can understand from restricting them from being poisoned onto weapons, just don't understand why emetic is as well.
