Tank in the middle zone.

• Don't let three in a row get claimed.

• Three adds spawn, that attempt to claim their section. 

• Remove adds by stacking the tank soak on them - only two tank soaks though, so one add will be left.

• Kill remaining large add and any smaller adds, away from the boss.

• Small adds come from portals.  Kill.

• Dodge swirlies, spikes, etc.
