In my opinion, I think that the drop rate is fine as it is already.
If the drop rate was so high, who would want to buy items and equips in the item shops?
And even if the drop rate is high, the items we get would not even fit into our item slot if it's fulled.
And you would keep running up and down to sell equips and hunting for equips again.
So, I think that the drop rate is already at it's best. If you think this server is lame, then don't play it.
