[Balance suggestion] Nerf ballista/priest combo, from old AOE

In the old AoE 1, I used to easily own the game by just making 10-15 Ballista and 2-3 Priests. That combo was OP and pratically able to destroy anything (was also good against Stone Throwers, by manually avoiding their hits).
I hope you will nerf it (in AOE Definitive Edition) in someway to balance the game, thank you :slight_smile:
