a good idea
Some of us are locked-on players where we have the camera forcibly follow us, without using the free cam, unless we have long range sniping abilities... a good idea, is if you have the locked cam have an option for 'floating'.. Where the camera can possibly float around a bit more freely instead of being hard-locked on your champ.. a good example, and hate me later, Dota2.. the way the locked cam is for that is beautiful.. it follows the mouse & extends vision a bit more, floating a bit further than the champs base spot.. I know this would come in handy while playing Nidalee from the red side. you can even see an active difference in Dota between hard locked, and floating if you play Meepo on there.. if your locked on the main one, it float, if your on one of the clones, its hard locked...
This is just an idea, and hate me later for the comparison... if its any consolation, i haven't spent a dime on that, & only have 40 hours logged on there, while i have well over a year of League experience, & have contributed well over 500$s to riot
