I've found that the vast majority of very good players, the world first players in the top 200 or 300 guilds or so don't really care what other people get. They know they're the best and they know it's skill is what makes them the best.
Then there's the people who find casuals getting gear "disgusting" that are almost always in the try-hard world 1000-2000 ranked guilds. They're mediocre at this game, and they put way more emphasis on gear than personal skill. Gear is the penultimate expression of how good someone is to them. Sorry broski, us good players don't care if others have 1 or 2 pieces of 895 gear. I'll be fully decked in 880+ gear soon while the world questers will still be 855 with a piece or two over 880, and all of the try-hards will be stuck with 870 ilvl.
