Actually if you look at the builders they are repairing their weapons...
BUT to the OP, heroes are different because they are immortal. All the laboratory is doing is giving you a new level of a troop to train in your barracks. The builder is upgrading something that never dies.. Idk tbh I'm done fighting this issue. We all want it, but SC won't fix it. I was going to gem my queen every time I got the DE but I decided against it. The last couple updates (content wise) were lack luster.
