Runes of Magic US / AU

I was under the impression only 2 things, depending on your class and the skill, determine bleed and poison effects: base physical damage, or base magical damage, I know I've tried testing ways to raise it but little seems to sway it one way or another

I've suspected that as well, would sure like to see some more definitive numbers on it, would make tweaking my skills a whole lot more efficient

The number for your main hand damage is what affects vamp bleed (this includes set skill damage bonuses, damage food, etc. so your chest piece, your full set bonus, your vn set if you have it all take affect). From my knowledge, bow damage affects the first hit, but not the tick for vamp. Bow damage does not affect bleeds.
