I'm not sure how long you've been away from the game but it would be my suggestion to keep poison off your template if you are intending to PK.
I too am back to the game, and I too have poisoning in my template. Players today are able to rid themselves of poison far too easy in my opinion. It's nothing like it used to be.
Unfortunately, I roleplay a poisoner so I have to keep it on my template but if I didn't I would probably drop it for a skill better suited to killing players.
