I mean you already have a perfect testing ground I don't see why you need to chain up another one and thus give NA players an advantage. And for that matter shouldn't there be a european PBE server since you need to test for many different languages anyways. A few minutes or even hours isn't enough time to see a full test of a product. For example if we test at 4am, it's not the same as testing at 4pm. More players, different behaviour, different stresses on different systems. 24 hours is the bare minimum to get a full day of information across all behaviours. Even then, weekdays and weekends are different. PBE is a test of the system in a much smaller scale. Each region has different capacities and capabilities to handle different load - it wouldn't make sense to have the exact same amount of servers for EUW as RU for example. As such, they all have their own unique risks and challenges. We can compare some of them (IE: NA and BR might be comparative), but that's limited in it's usefulness. Ultimately it boils down to not launching everything on a whim, finding it fails, and taking down every single region with it. We then have 10x the amount of work to fix immediately since we've just taken down 10 regions rather than one small one. Staggered rollouts aren't an uncommon thing in any industry. You used Blizzards example of patching all at once - we do some things in that style (such as new champion launches) since we are fairly well versed in those, but entirely new products or huge changes need more soak time to ensure we're comfortable with their stability
After a patch the servers get flooded meaning that the influx of players already give you a huge variety of systems especially for such a huge game as League of Legends thus issues should be noticeable quite quickly. I don't believe you need a full day of gathering information especially because issues for certain systems are usually not solved in mere hours but in days and because League of Legends is so big that sample sizes of NA systems should already include most EU systems. PBE should be able to test everything software related on different systems meaning that PBE should resolve pretty much all software issues. The only thing PBE does not test is different language packages(I don't know why you leave those out in the first place since your european players and players of other regions have to go to your NA-based PBE server if they want to test content early which essentially makes the PBE server international and it would thus be a good idea to include it so players can report issues with the language packages) and if the servers of different regions can handle the influx of players or in other words PBE doesn't test the servers of different regions. You shouldn't have to do 10 times the amount of work since software issues can be resolved on all servers simultaniously. Only server issues would increase tenfold which shouldn't be of big concern as this work would be split among the people who manage the servers in their region. If there are similar issues on these servers those issues should be resolvable more quickly. If you are uncomfortable with launching huge changes simultaniously but you are already able to do it with champions because you have made experience with that shouldn't you at least test if you can release big changes simultaniously? I mentioned Blizzard because for a long time they did not do simultanious patches because of similar reasons however since they tried it they have made experience with launching patches simultaniously and they are now able to do it every time with barely any issues. Please correct me if I am wrong on this but this is my understanding of it.

There's many factors that go into it depending on what the product is. For example we might test "safe" Ranked changes on KR and NA - NA because it's a fairly stable shard in size and capacity and close to the developers, and KR because they're highly competitive - so it makes for a great amount of testing. However if it's less "safe" (IE: Might not be received well or is a huge change which has some risk), we might avoid KR specifically for that reason and go with a less competitive region. Another factor is language - if something goes wrong in EU, we have to message to numerous different languages. EUW especially also has a super large player base, so something "breaking" there will hurt a lot more people than a smaller shard. Conversely again though, if we're testing our changes to specific languages or localisations, EU may be great for that! It gets a lot of exposure vs NA which is EN only. Basically, there's many different thoughts and processes behind who gets what when, based around risk, potential impact, how helpful it is to test there (IE: Testing a German specific change isn't much use on NA!) etc.
Why does it have to be an entire day though? Shouldn't the impact of the change be noticeable in mere hours? I mean we live in the information age you might aswell be able to make a judgement on it in minutes.
