I'm a big believer that ilvl is a very weak indicator of someones abilities. I've seen people with i85+ that still suck at their jobs. I've seen people with i60 that are great at their jobs. For example I did some titan/garuda ex runs tonight with my healer which is only i75 and I was just as good if not better then the healer that was at least i80+. Rather then worry about someones ilvl you should really be focused more on their actual abilities. If the minimum ilvl requirement is 55 then it's likely a character with an ilvl.55 will be able to be helpful if they know their role well. People are too damn used to vastly overgearing/leveling content that the idea of someone who is the appropriate level for the content taking part that they start to panic :/
