So our options at hitting the drakes are:
Snap shooting all our lances - draws a lot of fire from the rest of their army
Take a Void Raven and hope to get the jump on them
Prescience from allied Farseer on a Ravager or other unit.
ADL + QG
Other allies such as IG Hydras etc.
Which of these (and others you'd like to add) have people found effective and also fit with the rest of our army so that they still get utilised against armies with no flyers/drakes?
