I think in Avatar, a waterbender could only bloodbend under a full moon becauase it is a very advanced and powerful abilaty and they need and extra boost of power.

If a waterbender were just very powerful, then it makes sense that they don't need the full moon, just a moon. (but never in broad daylight, that would be pushing it, don't you think?)

In ATLA, the technique was relatively new, so it could not have been refined by many generations (same with lightning), like other forms. And the only known users were a teenager and an elderly woman. But later, obviously, someone did finally refine it.

Also I think that it's possible Katara could theoretically preform this feat,  she's probably still a better bender than Tarrlock,  but do to her resentment of it, she never practiced and just never used it ...I also refuse to believe any waterbender is better than Katara, but that's besides the point... ;P
