Good vid. If you stop and heal your cyclones between attacks then you can also keep there health up, espeically if you taking less than 5 mins of damage on each hit - keep it free as the say!
Also if you have enough Cyclones you can one shot the tempest and commandos before they get a shot away.
heres an under 40 no Uniques no Heroes just 1 Lead commando 4 preservers and 4 Cyclones with 1 Hailstorm under 40min repair
I have only used uniques. You could probably use missiles to take most out. Otherwise maybe you can get help
