Um, no. Just no. Changing your gear is literally rightclicking on an item (in a backpack, with the backpack on the skillbar, because that's how you use the UI properly) and then clicking Equip. Versus loading screens going to the End of Time. If you actually tried it, you tried it wrong.
That's more clicks than hiring a henchman you've got set up to craft. And you should already be in the Hall of Heroes, because that is where the Anvil and Whetstone are. If you are ONLY talking about things that can be crafted while wandering around in the world, then you may have a point.
Except you are still killing things slower and losing more time overall.
