I haven't multi boxed for about 5 years, but recently started wow again, and I kind of miss multiboxing.

What is the current state of multiboxing on WoW? I used to run heroics in WotLK with a Bear (main) and boomy (dps).

Is it still allowed?

I know now that WoW relies on procs to get the max damage - how hard is it to setup procs for different toons?

I plan on using Synergy Broadcast and a lot of macros.

Before I even start this. I'm asking, is it worth doing anymore?
