Lux Issues/Indicator Issues

Hi, I play with quick cast with indicator and I've noticed lux's hitbox on her ult is smaller than the indicator, width wise anyway. It's been such an annoying issue because I rely a lot on the indicators and theyre off on multiple champs too, not just Lux. And also on Lux, is there a way to let her ult go off while dying? Many times dying with the ult just about to fire is so irritating;; [sg-lux-2]

Additionally, Lissandra's Q should have an indicator like Sion's E, that would be majorly useful, but I'm probably only a small part who even uses indicator on quick cast so I'm not too hopeful.
