Furniture. You leveled your crafts up to 50 to make furniture. Congrats!

Honestly, if Yoshi doesn't want to make dungeon runs trivial, just make recipes that improve the dungeon armor/weapons slightly(like give it a +1 on its stats or something) that requires to actually have the dungeon armor. Something that'll actually make you feel "Hey I have a reason to level this crap, even if it's just a small one". Furniture. Bleh.

Oh, and bring back being able to repair other people's gear.
