I finally bought and used an Orc Hunter in combat and it seems... just fine, actually. It lists three abilities but the Snare and the Wild Call depend on their rage level. So I honestly don't see any issues with hidden abilities.
I do see that Training should say it controls vs. summons and wild call doesn't take your turn to use and probably ought to say so.
Wild Callworks just like hypnotize, actually in that you can even sacrifice what you control or cast beneficial spells on it. I also was able to stage it so the unit I controled broke control (it didn't die) to see if it becomes unattackable.... and it does.
So I'm going to make some updates.
In other news, when you get a chance can you check out the code for the Blizzard Spell (only freezing first hex) and the Phoenix fire breath (not always igniting but description implies it does). Thanks.
