The funny thing is that Mythic raiders (real ones and not pretended like OP) doesn't give a **** about people running around with high ilvl. What really matters is what you can clear or not. Only idiots are envy of (ilvl)number.
When WoW itemization will have an impact on skill, we will talk again. But so far, if you give 970 random gear (no tier, shitty trinket and so on) to 20 noob, they won't be able to clear even the first Mythic boss of current raid.
