I mostly suggest this because I noticed that level cost for renaming and enchantment is higher than vanilla and I believe that vanilla balances it pretty well. With the addition of grindstones in the village and pillage update, it helps rectify the enchantment cap. It does take learning but enchanting and repairing correctly will help players be better over all. I plan to make an enchantment guide at my res soon so anyone who is confused can learn how to do it best. It would just be nice to have enchantment costs be the same as vanilla so my guide can be complete. Naming stacks of items costing 15 levels also seems a little over the top to me as they only cost 1 in vanilla.
-1 Because I much prefer the ability to infinitely repair and enchant my tools over cheap levels as levels are basically freely available to anyone with public farms these days.
-1 Im going the have to go the same road as Pete for pretty much the same reasons. There are lots of Public farms available to everyone to farm experience and such. (I would be glad to show you PWU on smp8 if you would like to see. )
