You seem to think that my suggestions are radical changes to the system. Let me count up my suggestions over the last page (all the ones you deemed "non-canon"):
Water Whip threatens an area.
Water Whip does not provoke AoOs.
Water Whip uses wis to attack, since you don't actually hold it (Single Water Whip).
Ice Shards is left as it is right now, allowing weapons to be created.

Now, how many of those are radical changes to the system? Waterwhip is useless as Tentacle or Ice Shards can do exactly what it does now, only better, so why do you not want to change this again? I admitted that the wis to attack thing was settled a while ago (with me actually being here to see it), but it just makes sense to me. The Ice Shards thing, well, I see no reason to change it. It makes sense the way it is now, and there is absolutely nothing non-canon about it.

As for the bending skill thing, I'd prefer either just a skill, or base it off of class level. Fewer complications. And complications are a bad thing.
