OK, so I probably I misunderstood you... Yes a raft will help, but what I usually do is to slow down the first layer a lot and go 75% of the first layer height (S3D slicer) that will secured the support structure and in this way you don't need the raft. So if my print speed is set to 40, my first layer is set to 20 and if my layer height is 0.2 the first one will be 0.15.
I learned some time ago that the best secret to a perfect print is your first layer, if I don't get it right, I cancel the print and I start all over again.
