The 3.1 PTR has brought a lot of wonderful quality of life improvements, but here's one that players and GMs alike will undoubtedly appreciate more than a lot of them: you finally, finally get a confirmation window when you enter an instance that would lock you to it. You get the option to accept the lockout and stay in the instance or leave the instance and save your ID for later. You have 15 seconds to make said choice.
This means no more getting screwed out of heroics by some idiot who forgot he already ran Violet Hold today or any other of the myriad ways you can lose your ID for the day (or week). It's about time.
Our good friend BRK found this feature without even realizing it, as WI reader Brandon Tilley discovered it in BRK's screenshots of a PTR raid last night. Thanks for the heads-up on this exciting change, Brandon, and way to miss the boat, BRK!
