I still say as with many things in CF - try it yourself is probably one of the best ways to learn the downsides to a skill or ability that seems overpowered. Generally, enemies are going to use it in a best-case scenario for them, and avoid the downsides.

Some of the skill of the game is learning the ups and downs of things yourself, so I don't want to just straight spell out where it gets tough for it.

I will say some rather straightforward counters are either -

A) Like you mention, they run and drink. Keep them in the fight, and they can't heal.

B) They have to drink from a container. Can't drink if they can't see it.

C) People never think of this one, but if you know they're going to heal faster than you (a specific trait of orcs), then don't sit around nearby trying to beat them at the healing game. You're going to lose. Word, teleport, run, anything. Get yourself some distance and time, then heal. Sometimes you have to be willing to lose the battle to win the war.

so I don't really see this as a skill that is game-breakingly overpowered in the sense that taking a random average player and giving them this ability makes them unbeatable. By that count, bash still wins by far.

Personally, I'd say this is a great example of how orcs have a different feel than most other characters, and a way Scarabaeus did a great job putting them together.
