About the counters appearing not to work.

e.g. Resilience not reducing the boneshatter effects.
Edges to help resist poison never seeming to enable resistance.
Allegedly the demielemental transcendance not working against it.
Possibly the strong memory edge not helping against the forget effect. (I'm guessing on the last one.)

Also, the only thing stopping the class being a major major issue is the fact that the way to make them unbalanced is not common knowledge. I did make the same point earlier in that I said that as soon as this stuff became common knowledge then it would be a major issue for the game.

If I had managed to resist inhaled ko poison just once in many many attempts on me, I might consider it balance. There's no skill I've seen ko with such reliability, and it's longer duration than most others. Calling in others is not something Flaaayin is prone to do, but just imagine if he was? You'd have a thief able to ko people, wait for their effects to drop, with enough time for a gank to arrive, and then a gank where the victim has no skills (and can't run either). The build has the potential to create exactly this situation, and even a necro (the nearest comparison) doesn't have this kind of success rate or duration.

Imms are talking about ingredients from hell, but the reality is most of these ingredients are not from hell. I'm pretty sure of his main gathering grounds as I've noticed him going to certain areas repeatedly, and they are basically risk-free.
