The main problem is that the angle for purple team is different from blue team... If you can't just rotate the map to be more of a diamond <>, with the nexus at each end (like the camera of TT), then it would be nice if people could choose which sides camera angle they want (say you are placed on purple team, but you don't like that camera angle, you should have an option to flip the camera around so that purple team's base looks like how blue team's would normally). It's a minor annoyance that should be an easy fix, at least in my personal opinion
EDIT: It just seems basic to include the option to put a second camera from top lane purple side (like the one from blue side), it might not be an easy fix, but still it would be a nice OPTION, if you don't like it, you can play how it was originally, and not even be affected.
And why are people saying "don't lock camera"... it's not a problem of a locked camera, it's the problem of the angle, you cant change the angle you look at your side AT all even with unlocked camera, I don't play with locked camera, the only reason to is if you play with touchpad
