It's specifically for a weapon that is just a reskinned Warhammer. Not every weapon deserves this treatment at all.
Imagine an upgraded Confetti bow, enchanted for damage, never uses arrows. Yeah, now imagine that as an ego weapon. Yeah it'd be too ridiculous. There are many more joke weapons that really don't need anything, but the fact that the weapon is so like a Warhammer, one would think it would have upgrades similar to one, as well as repairs.
You went a bit nuts with your example at a attempt to refute my idea. Obviously I was not talking about prop weapons. I was talking about real weapons that cannot be special upgraded and or egoed. For example, a war sword cannot be special upgraded. Which ruins diversity in weapons.
Anywho i'm sure the people running this server knows how it felt to be ignored by nexon. Hopefully they will be listening to all suggestiions equally and responding with their own concerns and feedback
