I'm using an aggro hunter deck, and every time the bot plays Bittertide Hydra, I pretty much lose. Not only will it prefer it over other plays even when the enemy has board control, it'll also use it when the enemy's board control is the result of a lot of small minions -- the exact opposite of the best time to use the card. Case in point: I was up against a shammy who had 6 murlocs on board -- none of which did more than 2 damage -- the bot used Bittertide, and in the blink of an eye I lost.
It just doesn't seem to take into account the fact that every time Bittertide is damaged, you take 3 damage. I think it just sees it as an incredibly OP 5 cost 8/8.
I don't know how to post logs, but if you tell me, I'm sure I can find some.
