First off, let me just state that I am extremely happy that we have Latin American servers, just like we have servers all over the globe.
That being said, I am absolutely sick and tired of being stuck with players from Warsong and Ragnaros when attempting to do random dungeons. I understand that Blizzard wants us to be patient with “new players”, and to “guide them”, which is why they throw everyone together into one big melting pot when pulling players for random queues. That being said, if there is a language barrier, there will be no “guidance”, as it’s impossible to communicate with the players. The Latin American servers should draw from their own, separate, pool of players, so everyone who ends up in a dungeon together can effectively communicate.
Often times you’ll get thrown into a group with multiple Latin American players, and they cannot be removed due to having reached the kick limit, so you’re forced to wipe needlessly for hours, or leave the dungeon queue. This further penalizes yourself, as often you’re waiting 30+ minutes for a queue, and now have to wait 15 minutes to requeue on top of that.
I’m sure I’m not the only one who experiences this frustration. And as I said, it’s not against the Latin American players themselves. I am happy that they can experience the same game I can, however, I think it would serve everyone’s best interest if they had their own cluster of random dungeons, so everyone can speak the same language and be on the same page.
