Multiboxing - Boosting or Leveling? RAF Setup?

[MiRai]

So I think I am going to do the boosting.

But I still need input on how I should setup RAF...

A>B>C and A>D>E or A>B>C>D>E?

I'm thinking of A>B>C>D>E for the free months on ABCD, and for the rocket mounts on ABCD, but the other one would give me extra levels on my main account?

Here's a video I made back back in the day. The linking account portion still holds true... the rest of it pretty much doesn't anymore (one day soon™ I'll redo the video for new level 80 RaF).
