Hey guys i am rendering a scene that has some blisters crawling up some skin and am using displacements to achieve this, and i also have 2 light which only one is emitting shadows. Getting these shadows passes a taking twice the amount of render time than the actually beauty, does that sound normal?

It can be alright - depending on how you set up the scene, you might find that only having one light makes one shadow much stronger than it would have been with the two lights, where vray could have gotten away with much lower sampling. Have a play with using higher aa samples in one render, then trying lower aa but higher subdivs on your single light instead - you might get nicer results.
