About Laurels...
No, no, no. Laurels are only awarded from doing dailies and monthlies starting from the patch. There might be something like you said later but honestly don’t worry about achievements for the moment. Too many misconceptions about this as it is.
The patch on the 28th will bring laurels to the Daily and the monthly. They are currently working on the system for achievement points. You will be given laurels for “back pay” but as some achievement can be done over and over and over they are figuring a system to limit those who have farmed achievement points in such a way. Also from what I understand is that U get a laurel for completing the achievement not by how many points u have.
