Then you need to start at the bottom of the barrel either by starting with those sherpas or those in between. Also, I never bother going for LFG posts that require completions, or raids emblems. I would usually target post that are chill or "willing to learn" post. You don't really need a sixth sense to know what to look for raid post, it just takes some trial and error to do that... and know how to get some attention correctly... Finally, I curved my luck for my first raid completion many years ago... and I curved it a step further with my first clan as they seemed impressed with my perfomance in a strike... :p
