First, I want to say, I LOVE GWFreaks, and I want to say thanks for all the great work put into it already.
Now on to the feature request...
I would like to see the equipment tab and equipment builder parts of the program include the more recent changes to the way equipment is handled in the game. Namely, insignias, as opposed to specific armor art sets having specific stats, and also Common Runes such as Runes of Attunement and Runes of Vitae.
Adding the Common Runes to the program shouldn't be too difficult as it would simply require adding some content to the existing Runes pane in the equipment tab. Adding the Insignias, on the other hand, might require a re-work of the equipment tab interface.
Basically, I'm just a little tired of using the equipment builder to create a new item for each new character I design just so that I can put together an equipment set that includes the look, stats, insignias, and runes that I actually intend for the character to have.
That would be great if you could make that change, but until then I'll just keep making "custom" items with the equipment builder :).
