The answer is staggered thunderstorms (do not waste them by blowing more then 1 at a time)

If your thunderstorms are all on cooldown just spread out into a box pattern, then you do one of 2 things:
1.) if they are on your lead guy tap follow so they all auto face you, tap a broadcasted packpeddle to stop them and nuke away,
2.) if they are on an alt just face the alt with your main, tap follow, tap broadcasted back peddle, and nuke (usually you can only pull of a shock as your alt getting beat on will return to you as well, unless he is stunned)

thats what i do anyway, works for me

When we get nova totem stuns back, you can stagger drop these while your spreading out to make things easier. You can use a warstomp here as well, though the totems will work alot better
