On my Earthen, I accidentally used this random spell that showed up on my bars - the Everywhere all at once spell. Then realized I may have made a huge mistake. Sure enough, all of my maps have been revealed and when I tried exploring some random zones I had not gone to yet, I did not discover anything.
A lot of people think this spell won’t affect exploration xp, but that is not close at all to my experience. Possible bug? Earthen alts BEWARE!!! DO NOT listen to people online that say you can use this spell. Blizz, please fix
