Hello all!

I'm a Legion baby, very new and didn't realize multiboxing was a thing until recently! I want to give it a try but I had a few questions first:

I have Legion currently (WoW1) and also ended up with a second Starter Edition (WoW2) - not sure how I got that honestly but it doesn't matter. It says I can upgrade WoW2 to the full game (thru WoD of course) for $10 when I log in to it. If I were to create two new toons would I be able to multibox them up to 100 with my Legion WoW1 and the Upgraded Starter Edition (WoW2)? Or do both WoW1 and WoW2 have to be Legion?

Obviously leveling them past 100 would require Legion, but my plan would be to multibox enough to earn enough gold for tokens to pay for Legion for WoW2. And then further Legion licenses possibly down the road. Ideally I'd like to pay as little real-world money as possible but I can shell out a little here or there.

Thanks!
