Isn't it all personal preference? For me, I prefer it unlocked. I can see more, as well as what's happening, and I can pay attention to other areas around me easier.

This really isn't a conversation about the right way or the wrong way, it's up to the individual player. That's why there is the option.

Who cares?

It's preference. For me, locked limits your visibility. Since you don't understand what people are saying, I made it simple for you and have pictures! yaaay


Picture number 1, Locked View:
With locked view you are restricted from what you can see further in your lane and you have excess, unnecessary space behind your champion.

Picture number 2, Unlocked View:
The glories of having an unlocked screen gives you flexability. Without moving my champion, I can now see further down my lane and into the top bushes.

Picture number 3, Unlocked View:
With little effort, I can now see more down the lane.

Picture number 4, Unlocked View:
And now I can view the river and its bush.

Think about it like driving with mirrors. You don't always stare out your rear-view mirror, do you? No, you check your mirrors at the side of your car too

Roll on if that's your thing.

But...

You simply can't be as acutely aware with a locked screen. Minimap's great for letting you know someone's in a lane, but not exactly where they are in a lane and would cause you to have a hell of a time playing champs with globals.

The visible area of the map is far larger than your screen is showing you. If you lock to your champion you are not seeing 100% of the map. Minimap or otherwise.

Dude. The mini map should not be your only source of map awareness. There is so much information that you can only get by actually looking around.

How is top lane doing? You can tell by their heath bars on your screen that they are at half health, but how low are the enemies? Are they getting out maneuvered? Will they need help?

How is the team fight going? Should you take a bit longer and approach from bottom? Or should you go straight in to assist? Which will be better, tactically, for your team?

How can you tell which spells and skills have been used if you aren't there without an unlocked screen? Ask you team mates? if you asked me, I would ask you to stop wasting my time.

People talk about global ults(which is huge), but basic map awareness is key as well. I played roughly 300+ games with my screen locked before realizing what a huge handicap it is.
