Early acts levelling skill for witch, rolling magma alternatives?

Unless patch notes go really crazy I plan on playing glacial cascade of the fissure mines elementalist. but league starting rolling magma makes me want to logout after hailrake. And so I ask, what are your favorite levelling skills for witch that isn't rolling magma? I plan on swapping to glacial cascade mines at 38 when I get minefield support, so until then Im just looking for any skill.

As of now I have only tested stormblast mines + orb of storms which felt decent

ideally a cold/mine skill so I can minimize amount of respeccing I have to do but really not that much of a deal
