Can we fix the Cassiopeia buggy ult?

I tested it on the practice tool. If she is auto attacking the dummy and you ult in another direction, the ult will sometimes rotate slightly towards the target she is attacking instead of following the mouse. This make it inconsistent when playing.

Not only that, but the animation is weird in that I can't ever really tell how far the ult full range is as the particles kinda fade out at the end. I have to guess what the range is even as an experienced Cass player. My rule of thumb is it is about her full auto attack range.

Another thing is it kinda hard to tell when a target is facing you sometimes. Is it possible to get an indicator like fiora passive that make it clear when a target is facing you. Considering how delayed the Cass ult animation is it would help to have a little more accuracy.

Also, can we get a clear "target is poisoned icon". The purple one she has is very outdated and hard to see. This is 2017. Vital information on a champ kit should not be poorly represented visually. It would also be nice to see an indication of how long the poison will last.

Take Yasuo for example. His E indicates how long until he can dash to the same target. His R clearly indicated when he can ult.

What I'm asking for are not buffs, just clarity on what is happing on the screen so I can make better informed decisions about going all in or backing off.
