we have

we also have

Also 
so i thought it would be cool to have this kind of diversity.
Deep Terror Nami6 votesIt might be neat, but it actually doesn't fit into the game well because it's a different world where those languages don't exist. A lot of things that were put into the game in the beginning just don't meet the standards now so won't fly; if it doesn't fit reasonably into the lore somehow, they can't do it.
xXxKojixXx2 votesso what you really want is a Hispanic server.

This applies for any language pack.
Yi Bencheikh1 votesnope because i am in euw here it's alot of spanish people and i am pretty freindly with them they are cool.
Timethief491 voteswhat about the other languages? why spanish?
Yi Bencheikh1 votesbecause i like spanish :3 abit selfish sorry but i hope they could also do this for other world accents.
Leyin1 votesI think the big problem is to find voice actors for every language that can handle a good spanish accent, sure some spanish accent would be nice, but it should fit overall in the design and the lore of a champ. I think giving a champ a spanish legendary would be a better idea than a complete "spanish" champ
Killaburn1 votesye we this accent in lol and scottish, australian and irish too
KuroCaliber1 votesThis isn't Overwatch. Places like Britain Spain and France don't really exist. As Riot are more and more determined to make their own world, these reference accents are less common. Caitlyn, fiora, gragas and Viktor are all older champions. If you want an example of a voice retcon, look at Sion. Only example off the top of my head I can think of that is recent is kled with the southern accent, and maybe illaoi.
