So right now everyone pretty much agrees, equipping your troops is more important. The overall benefit effects more units, the items are cheaper to make gold wise and require fewer fragments (for most units)
I realize the repair thing is a gold sink and that item repair costs are apparently tied to the value of the total fragments put into it or something... So with that in mind, and without removing that gold sink.... Why do hero weapons have the same durability? Or any durability? I just dont think they should need repaired.
Consider that its 5 fragments to make a weapon for ONE guy, a weapon of basically same quality.
As opposed to 3 fragments for arming 20 people! And the durability/repair cost is the same ? Well, something should change at any rate. Eventually your units will all have nice gear, maybe the best gear, and you can finally work on gearing your heroes. I know heroes scale better and get lots of hp and such but it'd still be a good way to encourage gearing heroes, i've found some items for my heroes but i dont use them, not worth the repair cost compared to equipping my troops.
