Malzahar's passive
Malzahar's passive shield is getting popped by first cast on Nocturne's ulti globally wherever you are(at least let him retain vision for it). It also gets popped Lux's E ability without it detonating. On the other hand, healing plants don't slow him on pickup and don't pop his shield.
Not that Malz is weak or anything right now, but I really think his passive should be popping when he takes damage to avoid all those weird(buggy?) and not obvious interactions.
