Is riot ever going to rework Ahri's Foxfire?

Now that Ahri is good and meta again, it seems like we need to talk about her W. It doesn't do very much and there's not a ton of skill involved with using it. It's press W and damage goes flying off all over. This isn't a very interesting skill to use, nor does it have much counterplay. It seems like this is the best place in Ahri's kit to add a little more skill expression (read: nerf for unskilled players).

I was thinking there's probably a couple of routes that riot can take to do something about this skill.

1. Turn it into a skillshot. This seems like the easiest option. You pick a direction or spot, and things in that direction/spot are set on fire.
2. Turn it into an auto-attack skill. For example the first 3 AAs generate a little foxfire and the forth AA sends them off to that target. Ahri has to expose herself to more damage but gets to do more damage for the risk. This might push her more towards DPS than assassin, but everyone hates assassins.
3. More her charm into Foxfire and rework her E skill completely. Ahri creates a foxfire at a location that charms enemies near it and sets them on fire when the charm effect ends. This would make Ahri more of a teamfighter and force riot to move her other power in her kit from early game to mid/late game... probably by nerfing her base damage across the board and buffing her ratios.
