If you want a dot character, a warlock might better suit your needs.
As for rogues... well, if you want to focus on dots, then I'd say you should go Sub to get Serrated Blades and Hemo.
But honnestly, I wouldn't do it, you have better options. There are only specific situations where you'd better use bleed effects (e.g. against a warrior with high armor and who can beat the crap out of you if you try to just trade blows).
