Long-standing bugs on Sion

Here's a list of bugs Sion has that hopefully will be resolved or at least I'll get a response to know that Riot is aware of them.

Sion's leap at the end of his ult does not proc sudden impact nor does it jump over small walls.

With a tiamat item, Sion's basic attacks will not have the effect when entering zombie mode sometimes unless you use the active first

Sion's Q hitbox is WAY bigger than the indicator

Sion's E does not properly display the armor shred shield icon on all targets hit

Sion's E can show up laggy or rubber band minions sometimes

Sion's ult direction can be reversed if the cursor is too close to the minimap on cast

Sion will continue to bleed out even when invulnerable (zhonyas, bard ult, tahm, Kayle)

Sion's ult recast aoe is bigger than the indication
