Hello. For anybody still having trouble to unlock full map.
Me and my husband had this problem and none of those coordinates helped, so we were spinning around hopelessly. Our maps finally unlocked at: 1512,1522. Very bottom of the map.
Before glowy abilities it was one of two ways of knowing somethings ready to be used. The other way was to look at your buff bar... Not particularly a good way when in some serious combat, even more so PvP.
There's quite a few procs that are just gone or don't happen anymore and now with the ability to swap your original class to another you'll hear some of them again, oddly enough. An example is an inquisitor turned marauder, I actually am fond of these sounds as it brings up older memories.
I have always played with sound because it's very useful to know when things go off and when I am under fire, it tells you a lot of information and used to tell more with these specific sounds.
I would honestly love to see a full return of these with ability to disable them. It's part of the class and when you're comfortable enough it definitely helps the potential of playing with less / no UI - something I rather enjoy from time to time in PvP. More features to make the UI minimalistic would be greatly appreciated imo.
