The jump in ilvl is a pattern, so it would be kinda weird it they were lower, honestly. It may have been to avoid people from going in "unprepared". Of course, it's hard to be spot-on, since sometimes a specific piece brings your ilvl down, but your performance is just as good. I'd say try to upgrade your lowest piece to get that ilvl up enough, even if stats are not as much to your liking.
