Anything regarding Shen's rework?

*When can we expect it to hit PBE?

*Will his Passive receive some sort of change?

*Will he remain a Tanky Fighter or will he become a Tanky Support like ?

Can you assure us that Riot is keeping Shen's lore in mind when reworking him (We all want Shen vs. Zed to happen) and staying true to his essence.
