From what i understand the devs have more important things to sort out you know an expansion that less than 7 months away they know it is an exploit while doing nothing now they are going to make sure it can't happen in future from 5.0 onwards so lv 50 to 60 blu has to be done differently stop fearmongering it is unneeded and just paints you as petty it took you longer than someone else to reach lv50.
The devs stance is simple its an exploit they don't wanna work on right now but have plans in 5.0 to counter it going forward and really it's an oh no someone got to lv50 with just water cannon have fun whacking lv8 mobs with your cane for abilities the very core of blu is tied to XD
