The repair cost is extremely broken. In this test I tried to repair a stone shovel with efficiency I. The cost is 34 levels, but it should be 3-4 at most. 34 would only be acceptable if the durability being regained was much higher (like diamond), and the tool had 3-4 enchantments on it.

Should have checked this sooner. We have been trying to figure out whats going on with this for 3 days. We thought it was some kind of mod conflict going on. Is there any ETA on when this would be fixed?

Seem to have a lot of players xp entirety taken even with a level 4, or even 24 levels of xp. Had one with 76 levels taken away with 6 levels needed to repair an item.

@Darkhax Will this fix be implemented into the 1.7.10 version?

Highly unlikely. At this point it is very difficult for me to work on 1.7.10 or backdate any of my projects. If you don't like the Enchanting plus 4 releases for 1.7.10 (I don't blame you if that is the case) you should try this release. It still has a few minor bugs that were around from before I took over the project, but it is a lot more stable.
