I Skimmed over a numbe rof the posts so if i missed something My appologies. first to the Op i think you are looking at the changes wrong

PF poisons are alot more dangerous than my experience in 3.5 (minus the high level ones with SoD effects) IF you play the right type of character you can easily stack them in your favour

If you can get alot of attacks in, even with low DC's theres a goo chance the oponent can Fail We were running Second darkness and our Barbarian got 5 1d3 or whatever hand crossbow bolts fired at her and had to make 5 saves.

Secondly in PF when you hit somone already poisoed the Saves get harder. So rapid shot multi shotting archer for example and somones going to die horribly.

The only real Nitpick i have is Poisons are extrmely easy to make in RL but need to be factored with these prices for game mechanic reasons. So no making Risin at the Adventurers campfire :P
