Q:
Effective Level
I was wondering about it too. While I suppose I do not need it most of the time it is always perplexing to see things removed from the gui.
It’s because mastery flat out replaces your level in any place it was previously shown.
before, you could not see your own level (on the left side of the screen) and couldn’t see other players levels at all; only the level they were scaled to. now, if a player has any masteries, those are shown instead.
You can also, I believe, find out your effective level by mousing over the area it used to be. At least, that’s what showed up for me when I was looking at my Mastery XP levels.
Good luck.
