Comment 3 for bug 571799

It seems to me that a blinded player already in combat could logically continue to hit, kick, pummel, and so forth -- but it also seems that their success rate and damage should be reduced by at least half, since they can't see their target to land their blows skillfully.

A blinded player not already in combat shouldn't logically be able to start combat, imho -- it seems logical that any target that didn't want to be attacked could very readily slip out of the way of a blind attacker.
