In 5.3 Purple team locked camera is EXTREMELY disorientating.
First off: I am not on locked 90% of the time. Only time my camera is locked on me is usually when walking through contested or potentially dangerous territory (i.e. river). I play mainly jungle. The way I "lock" my camera is by holding space (or in most cases tapping it to bring me back to my champ after looking in a lane while walking to a camp).
In 5.3 when on purple team locking the camera (or tapping space to go to your champ) no longer centers the camera but rather puts it so your champion is a little bit up and to the right. So if I'm in a 10 person fight, instead of knowing I'm always the center (in big fights I tend to lose myself [in the music, the moment you own it] among the chaos) I end up a little up and to the right. So if I play a game on purple I'll get used to whenever I put my screen on me real quick that it's off a bit but then if I play another game and am on blue side I am back to the center of the screen.
Yes, I know the whole "purple team angle disadvantage for locked" crap but I don't think that has a big enough impact to have two separate positions for locking you screen. The purpose of locking in the first place is so you are in the CENTER. And while this may not be game breaking I find it (and my friends did also) annoying and sometimes disorientating when you expect the camera to pop itself to where you are in the center.
