Not really. This is a bit like looking at the US, saying that thereās +100 languages spoken there, and then saying it wouldnāt make a difference to throw in Colombia (in a world where there was no ping issues obviously).
Why EU servers mostly function is because over 50% of all of the EU speaks English proficiently. The percentage of proficiency in younger generations has also increased like most of the rest of the world, and like always there will be positive correlation with internet use, wealth, interactions with English etc, that will all be correlated with OW users. Iād think an 80% guess for conversational English on the mostly younger EU players is conservative. The other critical factor here is there is no alternative for solo queue players. You canāt opt out to another language like German, French, or Spanish (or even smaller languages) without losing out on even more players. As a result English becomes the default lingua franca of lots of different players, and even people that donāt speak it conversationally will have learned basic call outs over the years.
Thereās actually a large scale study that tracks these kinds of things called the EF English Proficiency Index. There is no EU country that tracks worse than moderate proficiency. Interestingly almost all countries in EU track at High or Very High proficiency except the largest non Germanic speaking countries. This makes a lot of sense and can help us understand the Middle East situation. If you are in the Netherlands you cannot expect to speak Dutch to many people outside of the Netherlands, and the places you can go in a comparatively smaller country are far fewer. Itās no surprise that English proficiency became a super important goal for countries whose first official language(s) were spoken by few people. Italy, France and Spain become exceptions of the norm as you arenāt nearly as limited by only speaking one of those languages. That said they were the only āmoderateā proficiency countries in the EU, everyone else being high or very high.
The middle east is a totally difference scenario. English proficiency is extremely low in the middle east, and is actually decreasing generationally (+30 year olds are more likely to be conversational in English than school or university age kids). The least proficient country in EU is moderate proficiency, and the most proficient country in ME is low proficiency. Most of the ME are āvery lowā proficiency.
One of the major reasons for this is the ME uses a different lingua franca then English. Arabic is more widely spoken (+60%) in the middle east than even English in EU (+50%). Which means as long as youāre conducting your trade or doing your travelling within the ME, English is seen as a luxury. Additionally if your primary language isnāt Arabic, that will obviously be the best second language to be taught in school.
The conclusion is that comparing EU to ME is like comparing EU to SA except actually still worse. The two regions share a completely different common language. Make an EU only lobby and its likely 10/12 players will be able to understand each other at a conversational level. Make a ME lobby and itās likely 8-9/12 speaking the same language (probably even higher, but Iām being conservative because Iām not sure how much access to tech trends with being taught Arabic). Make a lobby evenly split between both and youāre likely to have 5 speaking English, 4-5 speaking Arabic, and 2-3 who canāt speak either. The result is you have 1 person on your team you can coordinate with, rather than the typical 4.
I donāt have any skin in the game because Iām not playing in EU, but it always surprises me how little people think about the comparisons they make. There are legitimate reasons why sharing servers between regions where almost no one shares a language in the most team based shooter is gonna cause problems.
