I’ve got an idea for phasing. Instead of having some NPC that you have to talk to, to phase, how about having a popup ask the player when they go into a zone if they want a certain timespan (expansion) that they want to phase into. With all of my toons, the npc in tirisfal is glitched out and doesn’t give me the option to phase to a different point in time. It’s getting pretty irritating. I’ve even switched to multiple lower level characters to try to go to UC and they are stuck in the BfA time frame also.
Classic Era does not have Phasing.
However MoP
and Retail do.
