I’ve been playing GW on and off since the original release, have about 1400 hours across 12 characters and the one thing I’ve never been able to get my head around is how to tell if a drop is valuable or not.

I get that some are valuable for the inscriptions like “Aptitude not Attitude” but what’s the difference between a rare bow worth 1e and a rare bow worth 15+ arms? Is it all about the skins? And if so, is there a list of rare skins that are worth selling?

Also how do you obtain these items?…
