This is false. Completely. The drop rates may be higher, but even if they were 90%, which they aren't anywhere near, there would still be people that didn't hit 32. I've gotten lots of raid gear. A few shotguns, a few arms, a few legs (despite having these items equipped so that perhaps the chance of them re-dropping would be decreased). I've got shards and energy to max multiple guardians. I have multiple exotics I can use to fill in any body slot, but I have never had a head or chest drop, and there are a significant number of people in the same boat.
