Precise trajectories of Cherubs' projectiles

Get miscalculated time to time

All focus in the world doesn't guarantee a bullseye every single shot

The most critical hit can be foiled by the right breeze

Entry points only come into view every now and then

Watching target
Waiting for the right moment to release arrow into the air

Helplessly flying by only to strike the person standing behind them

Words of sweetest honey senselessly dripping out of the open wound 

Have a tendency to heal hesitantly 

To maximize velocity 
I think Cupid should upgrade his weapon to a crossbow
