Minotaurs are great for your level. They grant quite decent experience and even though they don't carry much valuable loot you can always skin them for additional money income.
Doing Mino task is always worth it, especially in Fox's hideout when you also got a chance to meet a random spawn of The Horned Fox. After you get 5000 kills you are able to fight The Horned Fox and he drops Nose Ring which is pretty much valuable as of your level.
