Taric's stun duration should be longer on closer enemies

Taric's stun has always had that awkwardly useless part where the damage increases insignificantly based on the distance it travels. I've never been sure why; seeing as Taric is supposed to be a tanky, in-your-face kind of support, as shown by his two AoE spells and on-hit passive, it seems counter-intuitive to reward him for "landing" a targeted stun from a long distance, especially when the reward is so small that I don't think anyone's ever actually accounted for it when they're playing.

Since Taric is supposed to be a close range support, I think his stun should have increased duration when it travels short distances. This allows Taric's stun to have a little more strength for following up on cc'd targets and peeling without giving it too much power for making picks and brawling in lane. This also allows for a little more counterplay, since carrying the stun out once you're targeted with a dash/blink will not only move you to safety, but decrease the duration.
