After watching the arena fights I just have to ask this...

Why can orcs go from near or mostly dead to full health from drinking elf blood? ( I may be exaggerating on the swing from near dead to full life ) It seems a bit broken...

Referencing the Narzas vs Zodsled fight and my general experiences with orcs.

I can't really think of another skill or use case like this where there is no skill lag or delay on the action for it.

There should either be lag, delay on the healing (Ie they sleep and heal faster) or a limit to the amount the belly can hold.
