Prior to patch 4.0.1, most battlegroups in Europe had a handful of non English speaking realms. Being on an English speaking horde realm, I could face a German alliance team in a BG, but never team up with them. With the 1 big pool now, it's pretty awesome ... had a couple of Germans in my team who did not speak English whatsoever. The 3 Frenchies refused to talk English as well. Which resulted in most people just speaking their native language in BG chat. Awesome. Getting the team to follow some basic tactics in the average BG wasn't simple before, but now it's getting even better.

It's kinda hard to grasp the reasoning and motives of the person @ blizzard who came up with this concept. 20k volt on his balls will prevent him from reproducing himself, that's the least that they could do.
