I was poking around the Mastery Challenges this evening and noticed there's a new Strength of Experience bonus. If we collectively earn 4,000,000,000 experience points by November 24 we all get some kind of easter egg. Did anyone else notice this? No one is talking about it.
I saw it. Usually these things are just for a PC desktop background or something. This time it seems that the challenge reward is virtual cab backgrounds (probably for some PC video call software).
