Quick Message- Some Hit Boxes Feel Really Off

This topic might not be as pressing to people as the "super high damage" and such, and it might just be my poor player skills and slow computer talking, but some hitboxes/ability indicators seem really off in game. Thresh hook and blitz q are prime offenders, really, questionable, sometimes, and karma q is shorter then the indicator at max range. I think cass q is a bit large too. Feel free to disagree, but anyone else get the same feeling? Or are their other hitboxes that are worse? And if these hitboxes and/or ability indicators are really off could we please get a fix? I get there's some satisfaction in knowing exactly when to pull the trigger on an ability to weave a hook through the minions or get that sion q a little more charge to get someone stunned right at the tip, it shows how comfortable a person is with a champion in a way, but for the worst offenders could we get some changes to how big the ability looks in game or make the hit box smaller to match the in game model? Would be greatly appreciated.
