One thing I'm curious about is how League would be when Arabic gets added.
Personally, Arabic can make things a bit more epic to hear, depending on the champion at least. I could be biased about this one, since I'm Lebanese.
Now, in case you're wondering:
"But...but...what if they add the Language and miss something, certain Arab would be offended that their own Language wasn't added?"
My answer: Don't worry. We have the traditional Arabic that literally every single one of us know (no accent, no different in terms etc.)
Audio-wise it would be interesting, however text-wise, it might be a bit tricky.
What do you think?
