Hi gang,Repairing items on the Empire adds an additional 5 XP costs on top of the vanilla costs, you can see the whole formula right here. One of the reasons for that, at least to my knowledge, is that gaining XP on the Empire is pretty easy.Although I somewhat agree (looking at 42 XP myself) there is also a problem: XP farms have been severely nerfed with the upgrade to 1.8. Endertopia? With all due respect but it is pretty much useless right now. Specifically in comparison to what it was before. And worse: the same applies to most of the player-build Endermen XP farms as well. There are some alternatives, obviously, but they don't match up to what you can gain from an Enderman farm.As such my suggestion: drop the additional 5XP repair costs and make repairing a true vanilla effort. Especially because the reason for it, the easily obtained XP levels, have been degraded when Endermen farms got nerfed.And on that subject: I think it would also prepare us for 1.9. Which pretty much radically changes the whole repair costs as well (so far I only read about it, I'm still testing this for myself). For what I know we no longer get increased repair costs. But... as mentioned: I haven't confirmed this myself yet.
