I'm having a hard time figuring out when or why you would build this item. Cassiopeia would be an obvious example, on account of the gratuitous E spam, but each tick of poison would reset the damage reduction.

You could use it to reduce the damage of the last three shots of a Jihn ult by 15%, which could be nice, but you also just spent 2800 gold on a magic resist item to block physical damage.

Most poke abilities that a frontline tank is going to eat regularly have cooldowns significantly higher than 4 seconds, which makes the passive ability essentially useless for that purpose.

The only way this item really shines in regular play is against DoT mages like Malzahar or Brand. Then again, DFT probably resets the damage reduction to, making us near-useless when DoT champions take the premier DoT keystone.

Honestly, the only place I can see this being used regularly is in URF, where "press the same key once every three seconds" is not only a valid tactic, but the optimal one for many champions.
