We've already taken a few hits, and we're not very strong; I don't know how many more we can take. If she's not going to move, I'd be inclined to try to drop some fire on her.
This is not to say we should forget about bucketsmacks entirely, of course. If we can race around enough that we catch her early in her cloud-forming, I definitely think it would be worth executing. But not so much after she has a decent cloud already formed.
