Ok here is my impression of the item system. The system as a whole works great but the colors seam out of whack.
For instance right now it is Blue - Master crafted, Green - Rare, Purple - artifact. Yellow for common.
I propose swapping the Rare and master crafted names and colors so it the end it looks like this.
Common -Yellow, Rare- green, Master Crafted - Blue, Artifact stays purple. This brings it in line with most games. and why should blue be called master crafted in the current build when you do not craft it??? So to me this just makes sense but open to others feedback too .
