How to deal with strong PD?

[VedalkenBear]

Zeldor: Still, the Staff of Storms negates that. MA TC also has quite good Cavalry. Placing them on the flanks and telling them to attack Rear at least has a chance to bypass the PD and get to his real troops.

Arrow Fend is another easy way to negate missile troops.

As far as Battle Evocations, Falling Frost is your best bet. Most of your CMs can cast it, and the damage should be devastating against Longbowmen. Ice Strike is later in Evocation, but all of your CMs can cast that. Your Earth Alchemists can Earth Power into Blade Wind, another deadly spell against longbowmen. Similarly, your Fire Alchemists can Phoenix Power into Falling Fires.
