Can we talk about Taric's Passive?

For those that don't know what Taric's passive is (while paraphrasing) "After using a spell Taric's next auto-attack gains 20% of his Armor and his Cooldowns are reduced by 2 seconds" which sounds amazing in theory, but doesn't really play to Taric's playstyle. See, Taric is a bursty point blank AoE damage champ, this passive however, wants him to weave auto-attacks in and out of his spells. It would be great, if Taric could "Dazzle, atuo-attack, Radiance, auto-attack, Shatter, auto-attack, Imbue, auto-attack" and get 80% of his armor in damage and a cumulative 20 seconds off his CD's (8 off dazzle, 6 off Radiance, 4 off Shatter, 2 off Imbue) But this never happens. In fact, Dazzle, auto-attack, Radiance/Shatter, barely happens before the enemy starts getting away. Like, I just feel this passive is out of place on a champion like Taric and would be better off on another champion, one who can take the time to weave auto-attacks in-between their spells (like Riven does).
