what setup to choose... im in a fuss :)

but it would require some movement issues to be resolved /follow works fine
for casters, but for multi boxing several melees it would require full control
over all 3. so a way to synchronise all three would be very cool indeed.

Melee's don't work for this very reason. Syncronising Movement is impossible, even with hardware to do effectively.

The best you could hope for is to have a Main melee and two ranged DPS.
