If I were to change the Itemaggedon event, I’d definitely limit the amount of limiteds, maybe 5 or less, and saved the rest for just regular hats. I’d also increase the quantity for cheaper items, since it was way too low and item hoarders were obviously going to grab them. As for ROBLOX copy items, I can present three right now.
Luduvo - Play, Create, and Connect → Ludicrous Floppy Hat With Unreasonably Large Bow - Roblox
Luduvo - Play, Create, and Connect → Red Glowing Eyes
Luduvo - Play, Create, and Connect → Midnight Commando - Roblox
There’s probably more, as well as some looser ones, but these are just the ones I have right now since its late for me.
