On some confirmation dialogs, it isn’t specific on what you are confirming. This can cause some unease as you may not be sure you made the right selection A few immediate examples:
Choosing a mastery
Unallocating a skill point
Unallocating a passive point
It would be nice if instead of “Are you sure you want to select this mastery?” It said “Are you sure you want to select Lich?”, for example. Same for unallocating points: “Are you sure you want to unallocate Mage Flurry?”
For applying skill & passive points, yes. But every time I’ve respec’d a passive or skill point I’ve had to click “ok” to respec it. I can provide screenshots if you wish.
