WHAT?! No way a free player won't get stats gain from a 24k item. I'm not sure if that's a typo, maybe you meant 2.4k item. That's more believable.
My lowest items are around 5k, and I'm a gold user. I suspect those "free" players are pulling your leg.
It's impossible for a free player not to get a stats gain from a 24k item. There, I said it.
Edit: Even with the crates, only the rares are above 24k. Uncommon and common are way under 24k items.
