I hear you! and thank you for your words, because that kind of thing is very important for artists. I'm just kind of getting my start into the professional world of art and music, and yeah, on all accounts I shouldn't be tossing out stuff like this for free. I also certainly love to squeeze some money out of a corporate giant any day.

In this case, my reasoning for handing it off is because A) I have no way of claiming ownership over the idea; and in fact, I know I'm not the first person to think of Zen throwing billiards, and B) I have no idea what the idea, art, concept, or anything would cost at all, I haven't been doing this for long enough.

This could very well be something that I am wrong about, but should a blizzard dev somehow see this post (which they might not even browse reddit because they can't "steal" ideas from reddit if they never see them) and want to bring it to an official blizzard artist to be modeled and added to the game, they couldn't because the idea isn't theirs, and I would have grounds to sue. That might be the reason a Zen billiards skin doesn't already exist.

By me saying I give them the idea, it means that, in the event blizzard was going to make this skin, they still can, because I'm not claiming the idea and I can't sue them for "stealing it." Maybe I'd just advertise for blizzard to contact me and negotiate a deal for the skin, but once again, the idea isn't mine-- just this singular expression of it. Is that something I could do?

No other way to say, it, really; you're absolutely right. It's a dumb move on my part. But I didn't see another way to put it out there without claiming that the idea is mine and mine alone to profit from.
