Yasuo did not need another shield this early in the game
now grants a shield. This is very good news for those who lack natural defensive stats and/or abilities who focus builds around crit, i.e. Marksmen. However there are a few melee who also benefit form the shielded crit item change. Yasuo has become even stronger in the early game. At 1 item, he now has upto 3 shields (Passive PD and Barrier) and a WW ability in the early game. He did not need another shield for early game, a time when he is supposed to be at his weakest.
Maybe change his passive to proc his item shields as well, or reset its amount of flow charge whenever another shield is used by him (not including shields from other champions), or set it to proc at only =< 30% remaining health like all the item shields do.
now.
build PD since the changes, and for good reason.
and vice versa. The unique passive doesn't interact or stack with each other, the Phantom dancer proc and Sterak does nothing. They all build stattik Shiv now.
