The passive has too many information. My suggest is split into two, one is kept as a passive, another move to an ability pasive (offensive to W?).

W: For a shield ratio, you should consider scale it with health (full, bonus, current, missing, ...). The armor stat is not high, has its as a ratio for a shield is not good.

For a tank, he doesn't have much threat in melee range. Taric has his passive, allow him to cast more spells. Galio and Nunu has their ultimate, and Nunu can also use his passive and W. Ivern has his E and allow him to has a good starting position for Daisy.

I have a similar kit for Galio Rework, where his W becomes his passive and he can pass it to his ally. They take X% reduced damage in 1 (or 2) second and store it as gray health, allow W to deal damage equal to the gray health gained, otherwise heal after 3s.

Unlike other ally-attacted champion (Kalista, Taric), this guy is too depend on his ally and a very unconvinent Armor. You should reconsider the Armor mechanic. Maybe he has two Armor instead. One is defend and one is offend. The offend is attached to his Q instead of the stacking mechanic.
