Two Items:
1) The mastery completion bar does stretches over to the icon that the player is working on. I thought my master progress was at 90% for 1-2 hours, when really it was at 100%
2) When a mastery is ready to train it would be nice to keep the pop up there longer or require a player to click on to dismiss it. If they was in the game, I would have known my mastery was ready to train.
Thank you.
