If skins like Elderwood Ahri are going to exist, we should be able to disable skin spell effects

Charm on the base skin is pink, in contrast to every other spell being white/blue. This allows you to react to Charm more quickly, because the moment you see pink, you know she threw a Charm.

And then we have Elderwood Ahri. All of her spells are pink. It's not immediately clear whether she threw her Q or Charm, because you no longer have a visual cue, and the visuals are also very similar ignoring the color. You have to waste time analyzing the animation and speed to figure out which ability it is, which inherently makes your reaction to it slower.

Skins like this should not be in the game. It's a clear cut case of selling power, but given that they're not likely to be removed, we should at least be given the option of always using base skin spell effects.
