@Meddler, What are your thoughts a keystone that reduces cast/channelling time of spells?

Would riot consider a keystone that speeds up cast times of delayed spells such as Q and R. Such that the spells animation would be about 10-30% faster.

Another example would be R would do full damage 10-30% quicker. Or damage over time spell would end quicker while doing the same damage.

Would that be something riot would consider for next season? If it is op, maybe it could be conditional.
