ilvl gear just improves stats to make the fight easier. Players should be judged on their achievements in game. I think we should have better access of seeing players' achievements to judge the quality of the player. Of course, downing twintania is more of an achievement than downing primals, even extremes. So I would like to see achievements that state not only when it was completed but the average gear ilvl you had. It might give clues that either they were carried or you have found a legendary awesome player.

Obligatory ending statement: I have ilvl95 weapon so this means I'm an awesome player
