"Crit XP vs Hit XP - Is this recognizable? Does it seem acceptable? Is there something that should give more/less xp, etc"

1. Severing crits should give as much XP as they do actual damage to NPC. (For now it's nothing usually)

2. I suggest, to filter criticals that can't affect NPC. For example, if NPC has no hands (severed hands), then no critical that affects hands should happen.
