I have noticed for that past couple of days. I was wondering if someone could pitch in on why this is. Whenever you are queued up for a warzone and decide to ride a taxi to another location on the world, and you're riding along and the queue pops up and you go into the warzone. Once you're done with the warzone, you are placed back at the starting taxi and you are also out the credits you paid for to use it earlier. I submitted in a ticket and it says that it was a feature, I feel that this is more of a bug and needs to be resolved.
