One of the toughest things to deal with in GD is the loot, because there are so many possible combinations of skills. It’s not just that you found some piece of gear with fire damage on it, it’s that it had fire damage AND vitality…or poison, or whatever other weird combo you may want to try.
I have most of the tabs filled, it’s tough to avoid that I think if you play a lot. You can actually salvage stuff and not just sell it, but all that does is give you components to collect instead of gear. It can be a good idea though because some of the crafted gear can be tough to fill out.
