Villager Trades

I think that the new villager trades are ok, but could be better. Perhaps to update and improve the villagers trades such as the Butcher, Shepherd, Armourer (the trades are good, but could be better aka emeralds for peak enchanted sword etc), Fisherman, and the Mason.

The Butcher's Trades seem odd.. like the amount of raw meat for an emerald seems like they're cheap-scapes. The trades seem useless too.. like a multiple amount of raw meat, for an emerald, then that emerald for one cooked meat seems a rip-off. Idk, seems useless and a waste of emeralds and meat that you can cook for the price of coal (an abundant resource). 

The Shepherd's Trades are also useless. C'mon the idea that you give so much wool and dye for an emerald is insane, and the Master level is only a painting, which is easily made in a crafting table, meaning that emerald can easily be saved up for better trades. If you wanted emeralds, the farmer is easy way to get it. This is the same for the Fisherman (instead with Fish).

The Mason is good, but for what you pay, the amount you receive is not the best.

Some new types of villagers to add could be a Wizard. This villager could gain this title by an enchanted table or a similar block. The Wizard's Trades could vary between Lapi Lazuli or Enchantment Potions to Enchanted Books or Potions. I don't mind if you change the name of this type of villager but this idea I think is good.
