When doing pledges or random dungeons I have the same frustrating experience almost every day: things go wrong due to a lack of communication, mechanics aren't done because the chat wasn't understood, hard modes aren't activated or messed up and many other things that could easily be solved with chat. Not every player has at least a rudimentary knowledge of the English language. So that the chat can at least be understood in terms of meaning. Personally, I don't understand how anyone would play an MMO and doesn’t understand a word of English. But many times exactly this is the case. (I don't want to name any explicit nationalities here)
There are so many people who make great add-ons for the game. Couldn't you create an add-on that integrates translation software and automatically translates the chat into your own language and, if necessary, your own chat into a foreign language? That would make so many things easier. Translating with google simply takes far too long. You have to copy the text, switch to desktop and back into the game and often the fight has already started and it's too late. It would also be very helpful if the addon displayed short tips in the group chat about the hard mode and special mechanics in certain languages before every boss fight. Of course, it would be best if such a feature could be integrated into the game straight away. But I'm afraid that won't be possible.
