how tf do I get good with this guy?

Fly: ~3s slowdown after using before you can do anything, survivors can camp window and vault as soon as it ends
Mage Hand: unless the loop is extremely short survivors get another loop around it unless you're already right on top of them (more so if you don't dispel their item that gives them haste when cast)
FotD: cannot get the timing for this right for my life unless survivors are close and at higher elevation
Dispelling Sphere: good for exhausting with staff of withering I guess

what am I missing here
