Demo Rotation with Wilfred involves a cycle of 2 setups.
The Big Tyrant Setup who involves GFG>VF>SB>SB>DOGS>Fill to 5>Hand of Guldan Spam for as many imps as you can.
Small Tyrant Setup who involves only VF>SB>Dogs>Fill to 5> Hand of Guldan Spam for as many imps as you can.
Hand of Guldan Spam is the step where you will weave Hand of Guldans, Shadow Bolts and Demonbolts.
On the pull it’s ok to push 6 imps on tyrant, afterwards as you are able to pool 2-4 demon cores for Tyrant you can and should push for 9 imps, if you want to farm logs then you need to step a little and push for 11 imps or more.
The Imps Might sound low in contribution as their value is only 1/5th of a Felguard, but they contribute in quantity and a 11 imps tyrant is as if you had 1 extra Felguard for Health.
