Not over much to talk about here. I understand it may be an issue of balance, but when I work my cogs off to create a four star weapon. I expect to be able to chew up tier one monsters. I understand that my damage output is higher than someone ,and four or five hits to kill _____ is impressive in comparison to the ten or so it takes a two star weapon. I just want to see something go down a little more quickly what with my sharp shiny new weapon I would expect a first tier monster to be felled in one to three hits "etc.". It isn't really a big thing just when you grind all the money to afford the energy to craft the blasted thing you would expect the lil critters to be little more then nuisances rather than something still capable of contending with you.
They make the weapons weaker so you don't outdo other players with less impressive gear. It also prevents farming for crowns with ease. Your weapon will only be full power at the proper depth.
