I'm really enjoying the item upgrade system so far, but there is one issue I'm having. With so much of an items future function hidden behind upgrades its really hard to evaluate new items, especially with how much of an investment it is to upgrade that and find out what they become.
Maybe this is in the game and I haven't found it yet, but some means of seeing the highest available tier of an item (Maybe in the upgrade screen somewhere) would do wonders for helping plan builds and set grind goals.
tldr: A way of seeing items final forms in game would be really helpful.
