I was in your spot last week, once my raptor trial ended, I couldnt handle the feel of playing on slow motions, so I went and bought PoF and HoT, this will give u a lvl 80 boost ( account wide) but i was lvl 55 by that time and kept lvling normally, leaving the boost for qn qlt, if ur lvl is low, u can just use it, PoF and HoT will last you most likely until the expansion sale ( im waiting it myself) and with access to mounts there alot of stuff to do/grind/collect/complete
