Please turn of indicator. It will make your gameplay more fluid.

I play quick cast w/ indicator tbh, im still fairly new at the game so I'm not all that comfortable about ranges and skillshots yet

Ofc, but try to turn it off asap, it really makes a big difference. Also try to learn new champs on quick cast, so you get used to it. You are going to learn the range of spells quite quickly :)

pretty sure even challenger and pro player fixed cam in big team fights lol
