The item level system is very good.
Of all the servers I have access to, only this one has this feature that I liked so much, only in my opinion, I believe that the percentage of 1%, could be 5%. Not needing to worry about anything at the moment, my friend, about the item levels.
I'll give you another example:
Today the game market is very competitive, I don't think players will have the patience to win that perfect item with a percentage of 1% in the box. It gets too tiring for the GunZ game in my opinion.
I am in favor of the item level, I just believe that players can achieve this a little easier with an example percentage of 5% more.
