That's hilarious. You guys would be in the middle of an op and suddenly a chunk of your guys go, "C'est mierde! non non non!", switch to French, and do whatever the f**k. I could see that as being a problem. We don't have any of these issue on our domestic servers, obviously. Worst we've got to deal with are the Quebecois and there aren't enough of them to matter. It is interesting, you guys trying to cooperatively work with all these tool groups. Not that you haven't been trying to make it work for decades.
Trying to make anything at all work with such a large number of people over the interwebs...good luck with that. I remember trying to coordinate even 40 man raids back in the WoW days. It really does boil down to people needing to be willing to just stop being obstinate dicks and agree to follow orders.
