Make severed limbs bleed more

[BaneOfGiygas]

Speaking medically, amputations really don't bleed a lot. The human body is EXCELLENT at constricting the veins and arteries near the affected site, if it wasn't cauterized by something already. Even decapitations aren't messy until a few minutes after.

They should, however, cause massive shock.

I remember hearing something like the former, yes. The veins that poke out of limb stumps actually curl back into the body in moments to preserve blood. There could be a set amount of immediate blood loss upon loss of a limb, but it shouldn't be continuous.

I also agree with the latter. Right now, losing a limb is almost comedically underwhelming; the problem lies more in the mobility issue and/or lack of grasping abilities, rather than in the fact that your limbs just flew off.
