Why is everyone doing mental gymnastics to try to avoid talking about the real problem?
The real problem is that a unit with that much range should not be good at killing mobiles.
Why does pillager have such high projectile speed? It seems faster than rocko rockets or rouge???
Why does it have AOE? How does that contribute to the artillery role? The AOE is too small to hit multiple buildings, so the only real thing it contributes is more mobile killing power.
Changing speed/turret just makes it worse artillery, while also slightly nerfing skirm potential. Why nerf arty role too? Artillery units are shit enough at killing buildings in zk already.
