Best double dps combs in MOP PVP with a frost mage?

Hey everyone! I'm planning to play MOP with a friend who's rolling mage, and we'll be focusing on 2v2 double DPS comps. I'm looking for recommendations on the best combinations, keeping in mind that we both have limited playtime.

I know some people might suggest rogue/mage since it's considered strong, but I suspect it requires more practice than we can realistically commit to. I was thinking feral/mage might be a good alternative since I'd have some healing utility as feral. But I know for retail at least, feral is really hard to be good, not sure how it is in Mop.

What would you recommend for the best 2v2 double DPS comps that don't require extensive practice time? For context, I'm a forever Duelist on retail, so I understand the fundamentals.

Thanks for any advice!
