Tournament items should be slightly better because they're considered far more difficult to get than luckyboxes. If you make the tournament items stats exactly like the legendary luckyboxes stats it would not be enough to motivate everyone in getting the tourney ones because why play hard for something that you can already have the chances to get by spending coins? Having just a unique model is not sufficient.
I agree that their damage should be equal to the legendary boxes but other stats can have a bit of tweaking. They can be more appealing than lbs by making them have slight less delay / less weight or even have extra weight when equipping them (just like the cat in the hat & just like the original Korean event items!)
